[0015] If the radar operation performance index is less than the radar operation performance index limit value preset in the radar detection database, the radar operation comparison result will be recorded as an abnormal radar operation result.

[0016] If the radar operation comparison result is that the radar is operating well, there is no need to issue an early warning for the radar's operating status, and the border and coastal defense detection radar continues to detect the border and coastal defense target detection area;

[0017] If the radar operation comparison result is an abnormal radar operation result, it is necessary to issue an early warning prompt for the radar operation status.

[0018] As a further solution, the network transmission index, the specific analysis process is as follows:

[0019] The operating status data of the border and coastal defense detection radar during the data transmission period is obtained, and the radar operating performance indicators corresponding to the border and coastal defense detection radar during the data transmission period are analyzed.

[0020] The transmission delay duration of the border and coastal defense detection radar network and the border and coastal defense detection control platform network during the data transmission cycle is ratio processed with the transmission reference duration preset in the radar detection database to obtain the transmission delay ratio of the border and coastal defense detection radar network and the border and coastal defense detection control platform network during the data transmission cycle.

[0021] The packet loss rate, transmission delay ratio, data transmission rate, channel utilization rate of the border and coastal defense detection radar network and the border and coastal defense detection control platform network during the data transmission period and the corresponding radar operation performance indicators of the border and coastal defense detection radar during the data transmission period are comprehensively analyzed to obtain the network transmission indicators.

[0022] As a further solution, the determination of whether to issue an early warning prompt for network transmission is made based on the network transmission comparison result. The specific determination process is as follows:

[0023] If the network transmission indicator is greater than or equal to the preset network transmission indicator threshold value, the network transmission comparison result is recorded as the first transmission comparison result.

[0024] If the network transmission indicator is less than the preset network transmission indicator threshold value, the network transmission comparison result is recorded as the second transmission comparison result.

[0025] If the network transmission comparison result is the second transmission comparison result, an early warning prompt for the network transmission is required.

[0028] The network transmission performance data of the border and coastal defense detection radar during the radar detection cycle is obtained, and the corresponding network transmission indicators of the border and coastal defense detection radar during the radar detection cycle are analyzed.

[0032] If the border and coastal defense security effectiveness index is less than the border and coastal defense security effectiveness index limit value preset in the radar detection database, the border and coastal defense security comparison result will be recorded as the second border and coastal defense security comparison result.

[0033] If the border and coastal defense security comparison result is the first border and coastal defense security comparison result, there is no need to use radar to issue an alarm to the border and coastal defense target detection area.

[0034] If the border and coastal defense security comparison result is the second border and coastal defense security comparison result, it is necessary to use radar to issue an alarm reminder to the border and coastal defense target detection area.

[0035] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0036] (1) The present invention obtains the operating status data of the border and coastal defense detection radar through real-time monitoring and analysis to obtain the radar operating performance index. Such real-time monitoring and analysis helps to timely discover potential problems of the radar system, such as equipment failure or performance degradation, so as to take preventive measures to ensure the continuous and stable operation of the radar system.

This helps to improve the response speed and accuracy of the border and coastal defense monitoring system and enhance the overall safety.

[0037] (2) The present invention transmits the detection data to the border and coastal defense detection control platform, thereby monitoring the network transmission performance data of the detection data in real time during the transmission process, which can help identify problems in network transmission, such as high packet loss rate, large transmission delay, etc., analyze the network transmission indicators, and compare them with the network transmission indicator limit values ​​preset in the radar detection database to determine whether it is necessary to issue an early warning prompt for network transmission, thereby ensuring that the detection data can be transmitted to the control platform in a timely and accurate manner.

This comprehensive analysis and early warning mechanism helps to improve the intelligence level of the border and coastal defense monitoring system, enhance the ability to respond quickly to potential threats, and thus effectively ensure the safety of the border and coastal defense.

A person skilled in the art can obtain other drawings based on the following drawings without creative work.

[0040] Figure 1 It is a schematic diagram of system module connection of the present invention. DETAILED DESCRIPTION

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] See also Figure 1 As shown, an embodiment of the present invention provides a technical solution: a radar system for border and coastal defense detection, including a detection radar operation monitoring module, a detection data transmission monitoring module, a detection data analysis module and a radar detection database.

[0043] The radar operation monitoring module is connected to the detection data transmission monitoring module, the detection data transmission monitoring module is connected to the detection data analysis module, and the radar detection database is respectively connected to the radar operation monitoring module, the detection data transmission monitoring module and the detection data analysis module.

[0044] The detection radar operation monitoring module is used to monitor and obtain the operation status data of the border and coastal defense detection radar in real time, analyze and obtain the radar operation performance index, and compare it with the radar operation performance index limit value preset in the radar detection database to obtain the radar operation comparison result, and determine whether it is necessary to issue an early warning prompt for the radar operation status based on the radar operation comparison result.

[0045] The detection data transmission monitoring module is used to obtain the detection data of the border and coastal defense detection radar on the border and coastal defense target detection area, and transmit it to the border and coastal defense detection control platform, thereby monitoring the network transmission performance data of the detection data in the transmission process in real time, analyzing the network transmission index, and comparing it with the network transmission index limit value preset in the radar detection database to obtain the network transmission comparison result, and determine whether it is necessary to issue an early warning prompt for the network transmission based on the network transmission comparison result.

[0046] The detection data analysis module is used to conduct a comprehensive analysis of the detection data and radar operation performance indicators to obtain a border and coastal defense security effectiveness index, and compare it with the border and coastal defense security effectiveness index limit value preset in the radar detection database to obtain a border and coastal defense security comparison result, and finally determine whether it is necessary to use radar to issue an alarm reminder for the border and coastal defense target detection area based on the border and coastal defense security comparison result.

[0047] In this embodiment, the above-mentioned border and coastal defense detection control platform serves as the core of the entire radar system. The border and coastal defense detection control platform is responsible for receiving, processing and analyzing data and results from the detection radar operation monitoring module, the detection data transmission monitoring module and the detection data analysis module. The platform integrates functions such as radar operation status monitoring, data transmission performance monitoring and detection data analysis, and realizes comprehensive monitoring and management of the border and coastal defense detection radar system. Through in-depth analysis of the collected data, the platform can evaluate the security status of the border and coastal defense, and make corresponding decisions and prompts based on the evaluation results to ensure the safety of the border and coastal defense.

[0048] The radar detection database is used to store preset radar operation performance index boundary values, preset network transmission index boundary values, preset border and coastal defense security effectiveness index boundary values, performance impact index corresponding to preset detection coverage ratio unit values, performance impact index corresponding to preset radio frequency signal power unit values, preset antenna beam allowable width, performance impact index corresponding to preset pulse repetition frequency unit values, preset pulse allowable width of transmitted signal, performance impact index corresponding to preset angle resolution unit values, performance impact index corresponding to preset distance resolution unit values, transmission impact index corresponding to preset transmission reference time, preset packet loss rate unit values, transmission impact index corresponding to preset transmission delay ratio unit values, preset channel reference utilization, transmission impact index corresponding to preset data transmission rate unit values, transmission impact index corresponding to preset radar operation performance index unit values, preset target movement allowable displacement, safety impact index corresponding to preset radar operation performance index unit values, safety impact index corresponding to preset volume unit values, safety impact index corresponding to preset average moving speed unit values, safety impact index corresponding to preset displacement proximity unit values, and safety impact index corresponding to preset network transmission index unit values.

[0049] Specifically, the operating status data of the border and coastal defense detection radar includes the detection distance, RF signal power, antenna beam width, pulse repetition frequency, pulse width of the transmitted signal, angular resolution and distance resolution of the border and coastal defense detection radar at the current monitoring time point.

[0050] It needs to be explained that the detection distance of the above-mentioned border and coastal defense detection radar at the current monitoring time point is obtained in real time through the radar's built-in distance measurement device, which uses the propagation time and speed of electromagnetic waves to obtain the detection distance; the radio frequency signal power can be directly obtained by measuring the power output by the radar transmitter through a power meter; the antenna beam width is obtained through the antenna control unit; the pulse repetition frequency is the number of pulses emitted by the radar transmitter per second, which is usually measured by a counter inside the radar, which records the number of pulses emitted by the radar transmitter in each time unit; the pulse width of the transmitted signal can be directly obtained by measuring the duration of the pulse signal generated by the radar transmitter with an oscilloscope; the angular resolution is provided by the radar's angle measurement device, which uses the Doppler effect technology to accurately measure the angular position of the target; the distance resolution is obtained through the radar's distance measurement device, which uses the time delay of the high-frequency pulse signal to calculate the precise distance of the target; the current monitoring time point refers to the specific moment when the radar collects data, and the radar's clock usually provides an accurate time mark.

[0051] In this embodiment, there is a mutually influencing relationship between the detection distance, RF signal power, antenna beam width, pulse repetition frequency, pulse width of the transmitted signal, angular resolution and distance resolution of the border and coastal defense detection radar at the current monitoring time point. These relationships jointly determine the overall performance and detection capability of the radar. The detection distance is affected by the RF signal power. The higher the power, the longer the detection distance is usually. The antenna beam width will also affect the detection distance. A narrower beam width can increase the energy density of the radar, thereby increasing the detection distance. The RF signal power directly affects the detection capability and anti-interference capability of the radar. The higher the power, the stronger the radar's detection capability for long-distance targets. A wider pulse width can increase the detection distance of the radar. The angular resolution is related to the antenna beam width. A narrower beam width can improve the angular resolution of the radar.

[0052] Obtain the distance between the border and coastal defense detection radar and the centroid of the target detection area at the current monitoring time point, and record it as the target distance.

[0053] It should be explained that the centroid of the target detection area is also called the geometric center or center of gravity of the target detection area, which is the average position of all points in the target detection area. First, the specific boundary and shape of the target detection area need to be clarified. This is usually based on map data, satellite images or radar scanning results. The target detection area is divided into multiple small areas (such as grids). Each small area has a certain center point. For the center point of each small area, its x and y coordinates are recorded, and the average value of the x coordinates of all center points is calculated to obtain the x coordinate of the centroid. The average value of the y coordinates of all center points is calculated to obtain the y coordinate of the centroid. The centroid of the target detection area is determined by the average value of the x and y coordinates calculated above, and the coordinates of the centroid are marked as (x, y). The coordinates of the coastal defense detection radar at the current monitoring time point are obtained as (x1, y1). The coordinates of the coastal defense detection radar at the current monitoring time point and the coordinates of the centroid can be calculated to obtain the distance between the coastal defense detection radar and the centroid of the target detection area at the current monitoring time point, and recorded as the target distance. The specific calculation formula is: , is the target distance.

[0054] The detection distance of the border and coastal defense detection radar at the current monitoring time point is ratio-processed with the target distance to obtain the detection coverage ratio of the border and coastal defense detection radar at the current monitoring time point.

[0055] Specifically, the radar operation performance index, the specific analysis process is as follows:

[0056] The detection coverage ratio, RF signal power, antenna beam width, pulse repetition frequency, pulse width of the transmitted signal, angle resolution and distance resolution of the border and coastal defense detection radar at the current monitoring time point are comprehensively analyzed to obtain the radar operation performance indicators. The specific analysis method is as follows:

[0057]

[0058] In the formula, is the radar operation performance index, is the detection coverage ratio, e is a natural constant, The performance impact index corresponding to the detection coverage ratio unit value preset for the radar detection database. is the RF signal power, The performance impact index corresponding to the unit value of RF signal power preset in the radar detection database, is the antenna beam width, The antenna beam width allowed by the preset radar detection database, is the pulse repetition frequency, The performance impact index corresponding to the pulse repetition frequency unit value preset for the radar detection database, is the pulse width of the transmitted signal, The pulse width of the transmitted signal preset in the radar detection database is allowed. is the angular resolution, The performance impact index corresponding to the angular resolution unit value preset for the radar detection database, is the distance resolution, The performance impact index corresponding to the range resolution unit value preset for the radar detection database.

[0059] It needs to be explained that the above-mentioned detection coverage ratio refers to the ratio of the detection distance of the border and coastal defense detection radar at the current monitoring time point to the target distance; the radio frequency signal power refers to the power of the signal emitted by the radar; the antenna beam width refers to the angle range of the beam formed when the radar antenna emits or receives electromagnetic waves; the allowable antenna beam width preset in the radar detection database refers to a standard value set in the radar detection database, which is used to determine whether the actual antenna beam width meets expectations; the pulse repetition frequency refers to the number of times the radar sends a pulse signal per unit time; the pulse width of the transmitted signal refers to the length of time required for the radar to transmit a single pulse signal; the allowable pulse width of the transmitted signal preset in the radar detection database refers to a standard value set in the radar detection database, which is used to determine whether the actual pulse width of the transmitted signal meets expectations; the angular resolution refers to the ability of the radar to distinguish the angles of adjacent targets; and the distance resolution is the ability of the radar to distinguish the distances of adjacent targets.

[0060] It needs to be explained that the performance impact index corresponding to the detection coverage ratio unit value preset in the above-mentioned radar detection database represents the numerical value of the influence of the detection coverage ratio unit value on the radar operation performance index. The radar detection database stores the corresponding relationship between the detection coverage ratio unit value and the corresponding performance impact index. For example, the detection coverage ratio unit value is input into the radar detection database, and the radar detection database can match the performance impact index corresponding to the detection coverage ratio unit value. At the same time, its value range in this example is (0, 1); the performance impact index corresponding to the RF signal power unit value preset in the radar detection database represents the numerical value of the influence of the RF signal power unit value on the radar operation performance index. The radar detection database stores the corresponding relationship between the RF signal power unit value and the corresponding performance impact index. For example, the RF signal power unit value is input into the radar detection database, and the radar detection database can match the performance impact index corresponding to the RF signal power unit value. At the same time, its value range in this example is (0, 1); the performance impact index corresponding to the pulse repetition frequency unit value preset in the radar detection database represents the numerical value of the influence of the pulse repetition frequency unit value on the radar operation performance index. The radar detection database stores the pulse repetition frequency unit value. The corresponding relationship between the bit value and the corresponding performance impact index, for example, the pulse repetition frequency unit value is input into the radar detection database, and the radar detection database can match the performance impact index corresponding to the pulse repetition frequency unit value, and its value range in this example is (0, 1); the performance impact index corresponding to the angle resolution unit value preset in the radar detection database represents the numerical value of the influence of the angle resolution unit value on the radar operation performance index, and the radar detection database stores the corresponding relationship between the angle resolution unit value and the corresponding performance impact index, for example, the angle resolution unit value is input into the radar detection database, and the radar detection database can match the performance impact index corresponding to the angle resolution unit value, and its value range in this example is (0, 1); the performance impact index corresponding to the distance resolution unit value preset in the radar detection database represents the numerical value of the influence of the distance resolution unit value on the radar operation performance index, and the radar detection database stores the corresponding relationship between the distance resolution unit value and the corresponding performance impact index, for example, the distance resolution unit value is input into the radar detection database, and the radar detection database can match the performance impact index corresponding to the pulse repetition frequency unit value, and its value range in this example is (0, 1).

[0061] In this embodiment, a smaller detection coverage ratio means that the radar can detect a limited area, which may cause certain key areas or potential threats to be missed, and in border and coastal defense monitoring, reduce the overall monitoring capability and safety of the radar; lower RF signal power will cause the strength of the radar signal to weaken, thereby affecting the detection distance and accuracy of the radar. At long distances or in complex environments (such as multipath effects, interference, etc.), the radar may not be able to effectively detect the target; a wider antenna beam width, even when it is greater than the preset antenna beam allowable width, will reduce the resolution of the radar, making it difficult for the radar to distinguish between multiple adjacent targets when detecting targets. In addition, a wider beam may also cause the radar signal to diffuse excessively in non-target directions, thereby reducing detection efficiency; a low pulse repetition frequency means that the time interval between two radar pulses is longer, which will cause the radar to blur or lose target information when detecting fast-moving targets, because The target may have moved a significant distance between two pulses; a smaller pulse width of the transmitted signal, or even less than the preset allowable pulse width of the transmitted signal, will cause the RF signal power to drop, thus affecting the accuracy of detection; low angular resolution means that it is difficult for the radar to accurately determine the direction of the target when detecting the target. In border and coastal defense monitoring, the radar will be unable to accurately determine the source and destination of the target, thereby reducing the accuracy and effectiveness of monitoring; low distance resolution will cause the radar to produce large errors when measuring the target distance. In complex environments, such as when there are multiple targets or there are obstructions between targets, low distance resolution may make it difficult for the radar to distinguish between different targets or determine the precise location of the target; therefore, through a detailed analysis of each parameter in the radar operating performance indicators, the radar's detection accuracy and stability of the target can be improved, the possibility of false alarms and missed alarms can be reduced, the radar can better adapt to various complex situations, and its effectiveness in different scenarios can be improved.

[0062] Furthermore, the determination of whether it is necessary to issue an early warning prompt for the radar operation status according to the radar operation comparison result is specifically carried out as follows:

[0063] If the radar operation performance index is greater than or equal to the radar operation performance index limit value preset in the radar detection database, the radar operation comparison result will be recorded as a good radar operation result.

[0064] If the radar operation performance index is less than the radar operation performance index limit value preset in the radar detection database, the radar operation comparison result will be recorded as an abnormal radar operation result.

[0065] If the radar operation comparison result is that the radar is operating well, there is no need to issue an early warning prompt for the radar's operating status, and the border and coastal defense target detection area can continue to be detected by the border and coastal defense detection radar.

[0066] If the radar operation comparison result is an abnormal radar operation result, it is necessary to issue an early warning prompt for the radar operation status.

[0067] In this embodiment, the radar operation performance index is compared with the radar operation performance index limit value preset in the radar detection database. If the radar operation performance index is greater than or equal to the radar operation performance index limit value preset in the radar detection database, it means that the current working state of the radar is stable and efficient, and its performance index reaches or exceeds the preset standard. Therefore, the radar operation comparison result is recorded as a good radar operation result. In this case, there is no need for additional early warning prompts for the radar operation status, because the radar is working normally, and the border and coastal defense detection radar will continue to detect the border and coastal defense target detection area to ensure the continuity and accuracy of monitoring; if the radar operation performance index is less than the radar operation performance index limit value preset in the radar detection database, there may be problems with the current working state of the radar, and its performance index fails to reach the preset standard. Therefore, the radar operation comparison result is recorded as an abnormal radar operation result. In this case, an early warning prompt for the radar operation status is required to promptly discover and solve the problem. The specific early warning prompt can display a clear warning message on the monitoring screen of the radar system, such as "Radar operation is abnormal, please check!".

[0068] Specifically, the network transmission performance data include the number of detection data packets sent by the border and coastal defense detection radar during the data transmission cycle, the number of detection data packets received by the border and coastal defense detection control platform during the data transmission cycle, the data transmission rate between the border and coastal defense detection radar network and the border and coastal defense detection control platform network during the data transmission cycle, the transmission delay duration and the channel utilization rate.

[0069] It should be explained that the number of detection data packets sent by the above-mentioned border and coastal defense detection radar during the data transmission cycle is obtained by checking the number of data packets sent by the radar recorded by the network monitoring tool built into the radar; the number of detection data packets received by the border and coastal defense detection control platform during the data transmission cycle is obtained by checking the statistical records of the received data packets by the data receiving and recording functions built into the border and coastal defense detection control platform; the data transmission rate of the border and coastal defense detection radar network and the border and coastal defense detection control platform network during the data transmission cycle is the data transmission rate of the network monitored by the network performance monitoring tool; the transmission delay duration is achieved by measuring the time required for the data packet to travel from the sending end to the receiving end, which usually involves adding a timestamp to the data packet to record the time of sending and receiving, and then calculating the difference between the two to obtain the transmission delay; the channel utilization rate can be determined by measuring the ratio between the throughput of the channel in actual use and the total bandwidth of the channel, where the throughput of the channel in actual use and the total bandwidth of the channel can both be obtained through the network performance monitoring tool; the data transmission cycle refers to the time span experienced in a complete data transmission process between the border and coastal defense detection radar and the coastal defense detection control platform, and this cycle usually includes the time required for each link such as data preparation, sending, transmission and processing at the receiving end.

[0070] In this embodiment, there is a close mutual influence relationship between the number of detection data packets sent by the above-mentioned coastal defense detection radar during the data transmission period, the number of detection data packets received by the border and coastal defense detection control platform during the data transmission period, the data transmission rate of the border and coastal defense detection radar network and the border and coastal defense detection control platform network during the data transmission period, the transmission delay duration and the channel utilization rate. The number of detection data packets sent by the border and coastal defense detection radar during the data transmission period directly affects the data transmission rate. If the number of data packets is too large, it may cause network congestion, thereby reducing the data transmission rate. A higher data transmission rate usually means a shorter transmission delay, thereby improving the real-time performance and response speed of the system. High channel utilization may cause more data conflicts and retransmissions, thereby increasing transmission delays.

[0071] The number of detection data packets sent by the border and coastal defense detection radar during the data transmission period is subtracted from the number of detection data packets received by the border and coastal defense detection control platform during the data transmission period to obtain the number of detection data packets lost during the data transmission period. This is then compared with the number of detection data packets sent by the border and coastal defense detection radar during the data transmission period to obtain the packet loss rate of the border and coastal defense detection radar network and the border and coastal defense detection control platform network during the data transmission period.

[0072] Furthermore, the specific analysis process of the network transmission indicator is as follows:

[0073] The operating status data of the border and coastal defense detection radar during the data transmission period is obtained, and the radar operating performance indicators corresponding to the border and coastal defense detection radar during the data transmission period are analyzed.

[0074] In this embodiment, the operating status data of the above-mentioned border and coastal defense detection radar during the data transmission period is the same as the operating status data of the border and coastal defense detection radar. Therefore, the analysis method of the radar operating performance indicators corresponding to the border and coastal defense detection radar during the data transmission period is also the same as the analysis method of the radar operating performance indicators. The radar operating performance indicators determine the amount of detection data generated by the radar per unit time. These detection data need to be transmitted to the control platform through the network. Therefore, the radar operating performance directly affects the transmission requirements and load of the network. The high resolution and long-distance detection of the radar usually mean a larger amount of data, which may cause network congestion, thereby affecting the data transmission rate and channel utilization. Therefore, if the radar operating performance indicators are not considered, the performance of the network under high load cannot be accurately evaluated.

[0075] The transmission delay duration of the border and coastal defense detection radar network and the border and coastal defense detection control platform network during the data transmission cycle is ratio processed with the transmission reference duration preset in the radar detection database to obtain the transmission delay ratio of the border and coastal defense detection radar network and the border and coastal defense detection control platform network during the data transmission cycle.

[0076] The packet loss rate, transmission delay ratio, data transmission rate, channel utilization rate of the border and coastal defense detection radar network and the border and coastal defense detection control platform network during the data transmission cycle, as well as the radar operation performance indicators corresponding to the border and coastal defense detection radar during the data transmission cycle are comprehensively analyzed to obtain the network transmission indicators. The specific analysis method is as follows:

[0077]

[0078] In the formula, is the network transmission indicator, l is the packet loss rate, The transmission impact index corresponding to the packet loss rate unit value preset in the radar detection database, is the transmission delay ratio, The transmission impact index corresponding to the transmission delay ratio unit value preset for the radar detection database, is the channel utilization, Channel reference utilization preset for radar detection database, is the data transmission rate, The transmission impact index corresponding to the data transmission rate unit value preset for the radar detection database, It is the radar operation performance index corresponding to the border and coastal defense detection radar during the data transmission cycle. The transmission impact index corresponding to the unit value of the radar operation performance indicator preset in the radar detection database.

[0079] It needs to be explained that the above-mentioned packet loss rate refers to the ratio between the number of detection data packets lost and the number of detection data packets sent, the transmission delay ratio refers to the ratio between the transmission delay duration and the preset transmission reference duration, and the channel utilization refers to the proportion of the channel utilized in a specific time period; the channel reference utilization preset in the radar detection database refers to a channel utilization standard value pre-set by the radar detection database; the data transmission rate refers to the amount of data transmitted through the channel per unit time.

[0080] It needs to be explained that the transmission impact index corresponding to the unit value of packet loss rate preset in the radar detection database represents the numerical value of the influence of the unit value of packet loss rate on the network transmission index. The radar detection database stores the corresponding relationship between the unit value of packet loss rate and the corresponding transmission impact index. For example, when the unit value of packet loss rate is input into the radar detection database, the radar detection database can match the transmission impact index corresponding to the unit value of packet loss rate, and its value range in this example is (0, 1); the transmission impact index corresponding to the unit value of transmission delay ratio preset in the radar detection database represents the numerical value of the influence of the unit value of transmission delay ratio on the network transmission index. The radar detection database stores the corresponding relationship between the unit value of transmission delay ratio and the corresponding transmission impact index. For example, when the unit value of transmission delay ratio is input into the radar detection database, the radar detection database can match the transmission impact index corresponding to the unit value of transmission delay ratio, and its value range in this example is (0, 1); the radar detection database presets The transmission impact index corresponding to the unit value of the data transmission rate represents the numerical value of the influence of the unit value of the data transmission rate on the network transmission index. The radar detection database stores the corresponding relationship between the unit value of the data transmission rate and the corresponding transmission impact index. For example, the unit value of the data transmission rate is input into the radar detection database, and the radar detection database can match the transmission impact index corresponding to the unit value of the data transmission rate. At the same time, its value range in this example is (0, 1); the transmission impact index corresponding to the unit value of the radar operation performance index preset in the radar detection database represents the numerical value of the influence of the unit value of the radar operation performance index on the network transmission index. The radar detection database stores the corresponding relationship between the unit value of the radar operation performance index and the corresponding transmission impact index. For example, the unit value of the radar operation performance index is input into the radar detection database, and the radar detection database can match the transmission impact index corresponding to the unit value of the radar operation performance index. At the same time, its value range in this example is (0, 1).

[0081] In this embodiment, a high packet loss rate means that some data packets are lost during the transmission process, resulting in incomplete information, which may cause problems such as false alarms and missed reports, seriously affecting the accuracy and timeliness of border and coastal defense detection; a high transmission delay ratio means that the time from radar detection to data reception on the control platform is too long, which may cause a lag in detection information and affect the rapidity and accuracy of decision-making; a large or small channel utilization rate, that is, when the degree of deviation from the preset channel reference utilization rate is large, excessively high channel utilization may cause network congestion, increase transmission delay and packet loss rate; too low channel utilization rate means that network resources are not fully utilized, resulting in resource waste; a low data transmission rate means that data takes a longer time to transmit, which reduces the real-time and efficiency of data transmission and cannot meet the requirements of border and coastal defense detection for rapid response; when the radar operation performance index corresponding to the border and coastal defense detection radar during the data transmission cycle is small, the quality of the detection information is reduced, affecting the reliability and effectiveness of border and coastal defense detection; therefore, by conducting a detailed analysis of the parameters in the network transmission index, potential network risks and abnormal conditions in the radar system can be discovered in a timely manner, preventive measures can be taken, the security and robustness of the radar system can be improved, and long-term stable operation can be ensured.

[0082] Furthermore, the specific determination process of determining whether it is necessary to issue an early warning prompt for network transmission according to the network transmission comparison result is as follows:

[0083] If the network transmission indicator is greater than or equal to the preset network transmission indicator threshold value, the network transmission comparison result is recorded as the first transmission comparison result.

[0084] If the network transmission indicator is less than the preset network transmission indicator threshold value, the network transmission comparison result is recorded as the second transmission comparison result.

[0085] If the network transmission comparison result is the second transmission comparison result, an early warning prompt for the network transmission is required.

[0086] In this embodiment, the network transmission index is compared with the network transmission index limit value preset in the radar detection database. If the network transmission index is greater than or equal to the preset network transmission index limit value, this usually means that the network transmission performance is at a normal or high level and can meet the current business needs or system requirements. Therefore, the network transmission comparison result is recorded as the first transmission comparison result, indicating that the current network transmission status is good and no early warning is required; if the network transmission index is less than the preset network transmission index limit value, this usually means that the network transmission performance is poor and may not be able to meet the current business needs or system requirements. Therefore, the network transmission comparison result is recorded as the second transmission comparison result, indicating that the current network transmission status is not good and attention needs to be paid. At the same time, if the network transmission comparison result is the second transmission comparison result, an early warning prompt for the network transmission is required. The specific early warning prompt can be set by setting an indicator light on the network management console. When the network transmission comparison result is the second transmission comparison result, the indicator light turns red to alert the operator.

[0087] Specifically, the detection data of the border and coastal defense detection radar for detecting the border and coastal defense target detection area specifically includes the volume of each detection target, the average moving speed and movement displacement of each detection target during the radar detection cycle.

[0088] It should be explained that the above-mentioned detection targets refer to various objects or entities that can be detected by radar within the border and coastal defense areas. These detection targets include but are not limited to ships, aircraft, drones, floating objects, etc.; the volume of each detection target usually adopts three-dimensional imaging technology, which constructs a three-dimensional image of the target by emitting electromagnetic waves and receiving their reflected signals. According to the size information in the image, the volume of the target can be obtained; the average moving speed of each detection target during the radar detection cycle is the moving speed of the target measured by the radar using the Doppler effect. When the electromagnetic wave encounters a moving target, the frequency of the signal reflected back will change. This change is proportional to the moving speed of the target. By analyzing this frequency change, the radar can calculate the target's moving speed. The radar system will continuously track the target and record its position changes over a period of time. By calculating the ratio of these position changes to time, the target's average moving speed can be obtained. The radar system can determine the target's position in space by continuously receiving the target's reflected signals and analyzing the time delay and amplitude information in these signals. By comparing the target's positions at different time points, the target's moving displacement can be calculated. In this embodiment, the radar detection cycle refers to the time interval for the radar to complete a complete scan and data processing. The radar detection cycle is randomly arranged according to actual detection needs and environmental conditions.

[0089] The displacement of each detected target within the radar detection cycle is ratio-processed with the target movement allowable displacement preset in the radar detection database to obtain the displacement proximity of each detected target within the radar detection cycle.

[0090] In this embodiment, the above-mentioned movement displacement refers to the displacement of the detection target moving toward the border and coastal defense area.

[0091] Furthermore, the specific analysis process of the border and coastal defense security effectiveness index is as follows:

[0092] The operating status data of the border and coastal defense detection radar during the radar detection cycle is obtained, and the radar operating performance indicators corresponding to the border and coastal defense detection radar during the radar detection cycle are analyzed.

[0093] In this embodiment, the operating status data of the above-mentioned border and coastal defense detection radar during the radar detection cycle is the same as the operating status data of the border and coastal defense detection radar. Therefore, the analysis method of the operating status data of the border and coastal defense detection radar during the radar detection cycle is also the same as the analysis method of the radar operation performance indicators.

[0094] The network transmission performance data of the border and coastal defense detection radar during the radar detection cycle is obtained, and the corresponding network transmission indicators of the border and coastal defense detection radar during the radar detection cycle are analyzed.

[0095] In this embodiment, the network transmission performance data of the above-mentioned border and coastal defense detection radar within the radar detection cycle is the same as the network transmission performance data, so the analysis method of the network transmission indicators corresponding to the border and coastal defense detection radar within the radar detection cycle is also the same as the analysis method of the network transmission indicators.

[0096] The border and coastal defense security effectiveness index is obtained by comprehensively analyzing the radar operation performance indicators of the border and coastal defense detection radar during the radar detection cycle, the network transmission indicators of the border and coastal defense detection radar during the radar detection cycle, the volume of each detection target, the average moving speed of each detection target during the radar detection cycle, and the displacement proximity.

[0097] In this embodiment, when analyzing the border and coastal defense security effectiveness index, it is crucial to consider the two parameters of radar operation performance index and network transmission index. This is because the performance of the radar directly affects the detection capability of the target, and the efficiency of network transmission determines whether these data can be timely and accurately transmitted to the control center for processing and analysis. The radar operation performance index is directly related to the radar's detection capability and accuracy of the target. For example, the greater the RF signal power, the farther the radar's detection distance; the higher the angular resolution, the more accurate the radar's positioning of the target. Therefore, when analyzing the border and coastal defense security effectiveness, the radar system's operating performance must be considered to ensure that it can effectively detect potential threats. The network transmission index reflects the stability and efficiency of the data transmission process. In the border and coastal defense monitoring system, the real-time and accuracy of data are crucial. If a high packet loss rate or transmission delay occurs during data transmission, even if the radar detects a potential threat, it will not be able to transmit the information to the control center for processing in time. Therefore, network transmission indicators are also important parameters for evaluating the security effectiveness of border and coastal defense. At the same time, the volume, average moving speed and displacement proximity of each detection target have an interactive relationship with the radar operation performance indicators and network transmission indicators. For example, the volume of the detection target may affect the pulse repetition frequency of the radar, thereby affecting the detection distance and accuracy; the average moving speed of the target may affect the radar's ability to track it; and the displacement proximity between the target and the radar is directly related to the radar's detection range and response time.

[0098] The specific analysis method of the border and coastal defense security effectiveness index is as follows:

[0099]

[0100] In the formula, is the border and coastal defense security efficiency index, e is the natural index, It is the radar operation performance index corresponding to the border and coastal defense detection radar during the radar detection cycle. The safety impact index corresponding to the unit value of the radar operation performance index preset in the radar detection database, is the number of each detection target, i=1, 2, 3, ...m, m is the total number of detection targets, is the volume of the i-th detected target, The safety impact index corresponding to the volume unit value preset in the radar detection database, is the average moving speed of the i-th detection target during the radar detection cycle, The safety impact index corresponding to the average moving speed unit value preset in the radar detection database, is the displacement proximity of the i-th detection target within the radar detection cycle, The safety impact index corresponding to the displacement proximity unit value preset in the radar detection database, It is the network transmission index corresponding to the border and coastal defense detection radar during the radar detection cycle. The security impact indicator corresponding to the unit value of the network transmission indicator preset for the radar detection database.

[0101] It should be noted that the volume of the above-mentioned detection target refers to the size of the space occupied by the target object detected by the radar in the border and coastal defense area; the average moving speed of the detection target within the radar detection cycle refers to the ratio of the distance moved by the target in a complete radar scanning cycle to the cycle time; the displacement proximity of the detection target within the radar detection cycle refers to the ratio between the movement displacement of the detection target within the radar detection cycle and the allowable displacement of the target movement preset in the radar detection database.

[0102] It needs to be explained that the safety impact index corresponding to the unit value of the radar operation performance index preset in the radar detection database represents the numerical value of the influence of the unit value of the radar operation performance index on the border and coastal defense security effectiveness index. The radar detection database stores the corresponding relationship between the unit value of the radar operation performance index and the corresponding safety impact index. For example, the unit value of the radar operation performance index is input into the radar detection database, and the radar detection database can match the safety impact index corresponding to the unit value of the radar operation performance index. At the same time, its value range in this example is (0, 1); the safety impact index corresponding to the volume unit value preset in the radar detection database represents the numerical value of the influence of the volume unit value on the border and coastal defense security effectiveness index. The radar detection database stores the corresponding relationship between the volume unit value and the corresponding safety impact index. For example, the volume unit value is input into the radar detection database, and the radar detection database can match the safety impact index corresponding to the volume unit value. At the same time, its value range in this example is (0, 1); the safety impact index corresponding to the average moving speed unit value preset in the radar detection database represents the numerical value of the influence of the average moving speed unit value on the border and coastal defense security effectiveness index. The radar detection database stores the average moving speed unit value and the corresponding safety impact index. For example, the average moving speed unit value is input into the radar detection database, and the radar detection database can match the safety impact index corresponding to the average moving speed unit value. At the same time, its value range in this example is (0, 1); the safety impact index corresponding to the displacement proximity unit value preset in the radar detection database represents the numerical value of the influence of the displacement proximity unit value on the border and coastal defense security effectiveness index. The radar detection database stores the corresponding relationship between the displacement proximity unit value and the corresponding safety impact index. For example, the displacement proximity unit value is input into the radar detection database, and the radar detection database can match the safety impact index corresponding to the displacement proximity unit value. At the same time, its value range in this example is (0, 1); the safety impact index corresponding to the network transmission index unit value preset in the radar detection database represents the numerical value of the influence of the network transmission index unit value on the border and coastal defense security effectiveness index. The radar detection database stores the corresponding relationship between the network transmission index unit value and the corresponding safety impact index. For example, the network transmission index unit value is input into the radar detection database, and the radar detection database can match the safety impact index corresponding to the network transmission index unit value. At the same time, its value range in this example is (0, 1).

[0103] In this embodiment, the radar operation performance index corresponding to the border and coastal defense detection radar during the radar detection cycle is low, which will directly affect the detection capability of the radar, resulting in an increase in missed reports or false alarms, thereby reducing the overall defense capability of the border and coastal defense system; the network transmission index corresponding to the border and coastal defense detection radar during the radar detection cycle is low, affecting the real-time and integrity of the radar information, and further affecting the accuracy and timeliness of the command decision-making, which may cause the command center to be unable to obtain accurate radar detection information in a timely manner, delaying the best time to respond to threats; in a complex environment, a large target may cover other small targets, resulting in missed reports; the average moving speed of the detection target during the radar detection cycle is fast, which will increase the difficulty of radar tracking and identification, especially when the target movement trajectory is complex or suddenly changes direction; the displacement proximity of the detection target during the radar detection cycle is large, which means that the detection target is closer to the border and coastal defense area, which will increase the threat level of the detection target to the border and coastal defense. The target with a greater proximity may bring a shorter response time to the defense system, increasing the difficulty of responding to the threat; therefore, by conducting a detailed analysis of each parameter in the border and coastal defense security effectiveness index, the urgency and severity of the threat of the detection target can be evaluated, thereby guiding the rapid response and deployment of the defense system.

[0104] Specifically, the final determination of whether it is necessary to use radar to give an alarm reminder to the border and coastal defense target detection area is based on the border and coastal defense security comparison result. The specific determination process is as follows:

[0105] If the border and coastal defense security effectiveness index is greater than or equal to the border and coastal defense security effectiveness index limit value preset in the radar detection database, the border and coastal defense security comparison result will be recorded as the first border and coastal defense security comparison result.

[0106] If the border and coastal defense security effectiveness index is less than the border and coastal defense security effectiveness index limit value preset in the radar detection database, the border and coastal defense security comparison result will be recorded as the second border and coastal defense security comparison result.

[0107] If the border and coastal defense security comparison result is the first border and coastal defense security comparison result, there is no need to use radar to issue an alarm to the border and coastal defense target detection area.

[0108] If the border and coastal defense security comparison result is the second border and coastal defense security comparison result, it is necessary to use radar to issue an alarm reminder to the border and coastal defense target detection area.

[0109] In this embodiment, the border and coastal defense security effectiveness index is compared with the border and coastal defense security effectiveness index limit value preset in the radar detection database. When the border and coastal defense security effectiveness index is greater than or equal to the border and coastal defense security effectiveness index limit value preset in the radar detection database, it indicates that the current security situation in the border and coastal defense area is good or within an acceptable range. The border and coastal defense security comparison result is recorded as the first border and coastal defense security comparison result, and there is no need to use radar to issue an alarm reminder to the border and coastal defense target detection area; when the border and coastal defense security effectiveness index is less than the border and coastal defense security effectiveness index limit value preset in the radar detection database, it indicates that the current security situation in the border and coastal defense area is not good or there is a potential risk. The border and coastal defense security comparison result is recorded as the second border and coastal defense security comparison result, and it is necessary to use radar to issue an alarm reminder to the border and coastal defense target detection area. The specific early warning reminder can display clear alarm information on the interface of the border and coastal defense monitoring system, such as "The border and coastal defense area security effectiveness index has dropped, please pay attention and take measures immediately."

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined in this specification, they should all fall within the protection scope of the present invention.
