Description

Technical Field

[0001] The present invention belongs to the technical field of weather radars, and in particular relates to a combined pulse ring elimination method, system, equipment, storage medium and terminal for a full-solid-state weather radar. Background Art

[0002] Weather radar is an important means of monitoring and warning of disastrous weather. my country's weather radar research, production and application are diversified. From the perspective of transmitter system, weather radar has evolved from magnetron system to klystron system and finally to all-solid-state system. Magnetron and klystron radars use high-voltage transmission to transmit the modulated signal through a high-voltage transmitter. The signal pulse width is fixed and there is no problem of combined pulse loops. With the continuous development of semiconductor materials and processes, the application frequency of high-power solid-state devices is getting higher and higher. Solid-state power devices have the characteristics of small size, light weight, high reliability, low operating voltage, high efficiency, good safety and temperature adaptability, etc. The application occasions of solid-state transmitters are becoming more and more extensive. Solid-state radar has low transmission power and must transmit wide pulses to increase detection capability. However, the use of wide pulses will bring technical defects, namely, the blind area of ​​wide pulses is large and the distance resolution is poor. In order to solve the problem of detection blind area, solid-state radar uses radar waveform design and combined pulses to solve the above problems. The three pulses of long, medium and short are spliced. The medium pulse is used to supplement the detection blind area of ​​the long pulse, and the short pulse is used to supplement the detection blind area of ​​the medium pulse. Finally, the detection blind area of ​​the radar is jointly determined by the pulse width and bandwidth of the short pulse. In the specific implementation, after the radar waveform design determines the required time width, bandwidth, center frequency and other information of the three pulses of long, medium and short, the radar signal processor generates the designed long, medium and short pulses and splices them, and then sends them to the up-conversion module for frequency conversion. Finally, the modulated electromagnetic waves are sent to the atmosphere for meteorological detection through the solid-state transmitter. When receiving, they are spliced ​​into a complete radial radar IQ signal according to the pulse timing, and then sent to the signal processing algorithm for spectrum estimation calculation. After obtaining the radar base data, it is drawn on the radar display and control terminal software. When calculating radar reflectivity, the parameters of the long pulse are substituted into the radar equation. Since the waveform parameters of the long, medium and short pulses are different, the detection capabilities are different. The radar constant calculated using the long pulse parameters is quite different from that of the medium and short pulses. The radar echo forms a fault at the intersection of the three pulses, namely a combined pulse ring.

[0003] At present, most radar manufacturers reserve correction positions in the software or configuration files. The staff manually modify the echo intensity correction values ​​of the corresponding ranges of long, medium and short pulses according to the difference in radar echo intensity at the junction of the combined pulses, so that the radar echo looks continuous as a whole. In actual work, the radar system is affected by various environmental factors and its own factors such as temperature, humidity, weather conditions, and its own electronic devices. The actual parameters of the radar are changing, while the echo intensity correction value is fixed. This causes the radar to have a combined pulse ring after a period of time. At this time, it is necessary to manually modify the parameters, and automatic ring elimination cannot be achieved. The combined ring affects the continuity of the radar echo, and the poor data quality affects the application of back-end meteorological products, which brings great inconvenience to the use of the radar.

[0004] Through the above analysis, the problems and defects of the prior art are as follows:

[0005] The radar system is affected by various environmental factors and its own factors, such as temperature, humidity, weather conditions, and its own electronic devices. The actual parameters of the radar are changing, while the echo intensity correction value is fixed. This causes the radar to have a combined pulse ring after a period of time. At this time, it is necessary to manually modify the parameters, and automatic ring elimination cannot be achieved. The combined ring affects the continuity of the radar echo, and the poor data quality affects the application of back-end meteorological products, which brings great inconvenience to the use of the radar. Summary of the invention

[0006] In view of the problems existing in the prior art, the present invention provides a combined pulse ring elimination method for a full solid-state weather radar.

[0007] The present invention is implemented in this way: a combined pulse ring elimination method for all-solid-state weather radar comprises:

[0008] Step 1, in a signal processor, the pulse widths of the generated long, medium and short pulses are counted to obtain the actual pulse widths;

[0009] Step 2, substituting the actual pulse width values ​​of each pulse into the radar constant calculation formula to obtain the radar constant C of each of the three pulses;

[0010] Step 3, then substitute the respective radar constants into the dBz0 calculation formula to obtain the dBz0 of each of the three pulses;

[0011] Step 4, at this time, the difference between the long, medium and short pulses dBz0 can be obtained;

[0012] Step 5, when calculating the radar reflectivity factor dBz, the dBz0 of the medium pulse and the long pulse are added to the difference between the dBz0 of the short pulse and the dBz0 of the short pulse to obtain their respective dBz values;

[0013] Step 6: The radar software selects the corresponding data for splicing according to the position of the three-pulse splicing point to form a complete radial data.

[0014] Further, the radar constant calculation formula is:

[0015] According to the radar equation, the echo strength can be calculated from the input signal power using the following formula:

[0016]

[0017] Where: is the radar wavelength (cm), is the antenna gain (dB), is the transmitted pulse power (kW), is the pulse width (μs), is the horizontal channel beamwidth (°), is the vertical channel beamwidth (°), is the input signal power (dBm), is the total loss of the transmitting and receiving branches (dB), is the distance (km), is the atmospheric loss, is the radar constant (dB).

[0018] Another object of the present invention is to provide a combined pulse ring elimination system for an all-solid-state weather radar, comprising:

[0019] The signal statistics module is used to perform real-time statistics on the pulse widths of long, medium and short pulses to obtain the actual pulse widths;

[0020] A radar constant calculation module, used to calculate the corresponding radar constant C based on the actual pulse width;

[0021] dBz0 difference calculation module, used to calculate the initial reflectivity factor dBz0 of each pulse according to the radar constant C and obtain the difference between them;

[0022] The reflectivity factor correction module is used to correct the dBz0 of the medium pulse and the long pulse based on the dBz0 of the short pulse as the reference value to eliminate the system deviation;

[0023] The data splicing module is used to seamlessly splice the long, medium and short pulse data according to the preset splicing rules and based on the corrected dBz value to form complete radial reflectivity data.

[0024] Furthermore, the signal statistics module monitors the pulse widths of the three types of pulses, namely, long, medium and short pulses, in real time, and inputs the actual width data into the radar constant calculation module to ensure real-time performance and accuracy.

[0025] Furthermore, the dBz0 difference calculation module generates difference data between the reflectivity factors by comparing the initial reflectivity factors dBz0 of the long, medium and short pulses for subsequent correction operations.

[0026] Furthermore, the reflectivity factor correction module obtains a corrected dBz value by adding the dBz0 value of the medium pulse and the long pulse to the difference between the short pulse, so as to ensure the consistency of the reflectivity factors between different pulse modes.

[0027] Furthermore, the data splicing module selects corresponding pulse data segments according to the three-pulse splicing point position rules preset by the radar software, and performs continuous splicing to form complete radial data, thereby ensuring detection accuracy and data integrity.

[0028] Another object of the present invention is to provide a computer device, comprising a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processor executes the steps of the combined pulse ring elimination method of the all-solid-state weather radar.

[0029] Another object of the present invention is to provide a computer-readable storage medium storing a computer program, which, when executed by a processor, enables the processor to perform the steps of the combined pulse ring elimination method of the all-solid-state weather radar.

[0030] Another object of the present invention is to provide an information data processing terminal, which is used to implement the combined pulse ring elimination system of the all-solid-state weather radar.

[0031] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present invention are as follows:

[0032] First, in view of the technical problems existing in the above-mentioned prior art, some creative technical effects are brought about after solving the problems. The specific description is as follows:

[0033] (1) The present invention provides the fundamental cause of the combined pulse ring from the perspective of the radar equation. In view of the currently common technical defects, a solution is provided from the perspective of the radar equation. The difference in the combined pulse detection capability is obtained by analyzing and calculating the combined pulse detection capability of the solid-state radar, and the difference is automatically compensated when calculating the back-end radar spectrum parameters, thereby achieving the purpose of eliminating the combined pulse ring.

[0034] (2) The present invention fundamentally solves the problem of combined pulse rings. After using this method, the all-solid-state weather radar no longer has the problem of combined pulse rings, and the user no longer needs to manually correct the correction values ​​of the long, medium and short pulses in the configuration file. This solves the observation application problem of the all-solid-state radar system, improves the quality of solid-state radar data, more truly reflects the actual weather process, and reduces the maintenance effort and cost of personnel.

[0035] (3) The present invention is not affected by changes in radar system parameters. When radar parameters are affected by changes in the working environment or its own electronic components, the combined pulse ring will still be eliminated because the differences generated are all in the radar constants. When calculating dBz0, the differences generated are all included in the differences in dBz0 of the three pulses. The correction is based on the short pulse and the dBz0 difference is added to calculate the dBz0 of the medium pulse and the long pulse, which automatically eliminates the intensity difference and prevents the combined pulse ring from appearing.

[0036] Second, when traditional weather radars measure the reflectivity factors of long, medium and short pulses, the different pulse widths lead to large system measurement deviations. Existing technologies usually perform splicing through fixed parameters or simple corrections. This method fails to fully consider the differences between radar constants and reflectivity factor baseline values ​​between different pulses, thus affecting the accuracy and consistency of the data. In addition, during the data splicing process, there is a lack of optimization methods for splicing point errors, resulting in poor integrity of radial reflectivity data, which restricts the accuracy of long-distance and short-distance reflectivity measurements.

[0037] The present invention provides a combined pulse ring elimination method for a fully solid-state weather radar. By taking statistics on the actual pulse widths of long, medium and short pulses, the corresponding radar constants and the reflectivity factor reference value dBz0 are calculated to eliminate the system deviation between the three pulses. At the same time, a splicing point optimization algorithm is used to seamlessly splice the corrected data to form complete radial reflectivity data. The present invention significantly improves the detection accuracy and data consistency of weather radars within different distance ranges.

[0038] The present invention effectively solves the measurement deviation problem caused by pulse differences in the traditional fixed parameter method by dynamically calculating the radar constant and reflectivity factor dBz0, ensuring the high consistency of reflectivity factor data in the three pulse modes of long, medium and short. In addition, the splicing point optimization method significantly improves the integrity and continuity of radial data and enhances the detection capability of the radar system under complex meteorological conditions. This innovative method greatly improves the performance of weather radar and is applicable to many fields such as weather forecasting, disaster monitoring and aviation safety.

[0039] The technical solution of the present invention has significant value in industrial applications. Through precise measurement and data correction, the weather radar's ability to detect atmospheric structure and meteorological parameters is improved, and it can be widely used in meteorological forecast centers, aerospace monitoring agencies, and natural disaster prevention and control departments. At the same time, the method also reduces the system maintenance cost caused by splicing errors, improves the service life and performance stability of radar equipment, provides important technical support for the development of the meteorological industry, and promotes the widespread application of all-solid-state weather radars around the world.

[0043] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] like Figure 1 As shown, a combined pulse ring elimination method for a full solid-state weather radar provided by an embodiment of the present invention comprises the following steps:

[0045] S101, counting the pulse widths of the generated long, medium and short pulses in a signal processor to obtain actual pulse widths;

[0046] S102, substituting the actual pulse width values ​​of the three pulses into the radar constant calculation formula to obtain the radar constants C of the three pulses;

[0047] S103, then substitute the respective radar constants into the dBz0 calculation formula to obtain the dBz0 of the three pulses;

[0048] S104, at this time, the difference between the long, medium and short pulses dBz0 can be obtained;

[0049] S105, when calculating the radar reflectivity factor dBz, dBz0 of the medium pulse and the long pulse are added to the difference between the short pulse dBz0 and the short pulse dBz0 to obtain their respective dBz values;

[0050] S106, the radar software selects corresponding data for splicing according to the positions of the three-pulse splicing points to form a complete radial data.

[0051] The all-solid-state weather radar uses a signal processor to perform real-time statistics on the three types of long, medium and short pulses emitted to obtain the actual pulse width of each pulse. These pulse widths are used to calculate the radar constant C corresponding to each pulse. The radar constant is an important indicator reflecting the parameters of the radar system and is closely related to the transmit power, receive sensitivity, beam width, etc. The accurate radar constants of the three pulses are calculated by inputting the actual pulse width.

[0052] Using the radar constant C obtained, the initial reflectivity factor dBz0 of the three pulses, long, medium and short, is calculated. dBz0 is the reference value of the reflectivity factor, which represents the measurement baseline of the radar in different pulse modes. By comparing the dBz0 of the three pulses, the difference between the pulse modes is obtained. These differences reflect the influence of pulse width on radar reflectivity measurement and are an important basis for subsequent data correction.

[0053] Based on the short pulse dBz0 as the reference value, the medium pulse and long pulse dBz0 are corrected. The correction method is to add the dBz0 value of the medium pulse and long pulse to the difference between them and the short pulse to obtain the corrected dBz value. Through this process, the systematic deviation between different pulse modes is eliminated, so that the radar reflectivity factor has higher data consistency in different distance measurements.

[0054] The radar software seamlessly splices the corrected long, medium and short pulse data according to the preset three-pulse splicing point rules. The location of the splicing point is determined by the radar ranging accuracy and data coverage. During the splicing process, data fragments within the corresponding distance interval are selected and continuously spliced ​​according to the corrected dBz value to finally form complete radial reflectivity data. This splicing method can effectively improve the detection accuracy and data integrity of all-solid-state weather radars within different distance ranges, and provide high-quality reflectivity factor data for meteorological forecasting and research.

[0055] The radar constant calculation formula provided in the embodiment of the present invention is:

[0056] According to the radar equation, the echo strength can be calculated from the input signal power using the following formula:

[0057]

[0058] Where: is the radar wavelength (cm), is the antenna gain (dB), is the transmitted pulse power (kW), is the pulse width (μs), is the horizontal channel beamwidth (°), is the vertical channel beamwidth (°), is the input signal power (dBm), is the total loss of the transmitting and receiving branches (dB), is the distance (km), is the atmospheric loss, is the radar constant (dB).

[0059] like Figure 2 As shown, a combined pulse ring elimination system for a fully solid-state weather radar provided by an embodiment of the present invention includes:

[0060] A statistical module is used to count the pulse widths of the long, medium and short pulses generated in the signal processor to obtain the actual pulse widths;

[0061] The calculation module is used to bring the actual pulse width values ​​into the radar constant calculation formula to obtain the radar constant C of each of the three pulses; then bring the radar constants into the dBz0 calculation formula to obtain the dBz0 of each of the three pulses; at this time, the difference between the long, medium and short pulses dBz0 can be known; when calculating the radar reflectivity factor dBz, the dBz0 of the medium pulse and the long pulse are added to the difference between the short pulse dBz0 and the short pulse dBz0 to obtain their respective dBz values;

[0062] The radial data acquisition module is used by the radar software to select corresponding data for splicing according to the position of the three-pulse splicing point to form a complete radial data.

[0063] Another object of the present invention is to provide a computer device, comprising a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processor executes the steps of the combined pulse ring elimination method of the all-solid-state weather radar.

[0064] Another object of the present invention is to provide a computer-readable storage medium storing a computer program, which, when executed by a processor, enables the processor to perform the steps of the combined pulse ring elimination method of the all-solid-state weather radar.

[0065] Another object of the present invention is to provide an information data processing terminal, which is used to implement the combined pulse ring elimination system of the all-solid-state weather radar.

[0066] The present invention is specifically implemented:

[0067] In order to solve the above technical problems, the technical solution provided by the present invention is: no longer using the waveform parameters of the long pulse to calculate the dBz0 of the three pulses, but calculating the dBz0 of each pulse respectively according to the waveform parameters of the long, medium and short pulses, and calculating the dBz0 difference between the short pulse and the medium pulse, and the dBz0 difference between the medium pulse and the long pulse. When calculating the radar reflectivity factor dBz, the difference between dBz0 is automatically compensated to dBz.

[0068] like Figure 3 The specific scheme is as follows: statistics are taken for the long, medium and short pulses to obtain waveform parameters such as actual pulse width and transmission power, and the waveform parameters of each pulse are substituted into the calculation formula of the radar constant C to obtain the radar constants of the three pulses respectively, and then the respective radar constants are substituted into the calculation formula of dBz0 to obtain the dBz0 of the three pulses respectively. At this time, the difference between the dBz0 of the long, medium and short pulses can be known. The radar reflectivity factor dBz is calculated by factors such as dBz0, signal-to-noise ratio, distance correction, and atmospheric attenuation. When calculating the dBz of each of the three pulses, the short pulse remains unchanged, and the medium pulse adds the dbz0 difference with the short pulse on the basis of its own dbz. Similarly, the long pulse adds the dbz0 difference with the medium pulse on the basis of its own dbz, thereby achieving the purpose of automatically eliminating the solid-state radar pulse combination ring.

[0069] When the radar is actually working, the system parameters will change with the working environment and its own electronic devices and other factors. In the radar equation, it is mainly reflected in the radar constant and the signal-to-noise ratio. The weather radar online real-time calibration system can accurately and real-time obtain the pulse power, noise floor, pulse width, etc. When the radar system changes, whether it is pulse power, noise floor or pulse width, it will be reflected in the radar constant. The present invention can accurately obtain the difference between the detection capabilities of the three pulses themselves and the parameter changes caused by changes in the radar system. The difference in dBz0 between the three pulses is obtained by calculation and the difference is automatically compensated based on the short pulse when calculating the radar reflectivity factor, thereby achieving the purpose of eliminating the combined pulse ring.

[0070] The combined pulse ring elimination method of all-solid-state weather radar mainly relies on pulse width statistics and radar constant calculation in radar signal processing. In the signal processor, the widths of the three types of pulses, long, medium and short, are counted to obtain the actual pulse width value. According to these pulse widths, they are substituted into the calculation formula of the radar constant to further calculate the radar constant C. The radar constant is an important parameter to measure the performance of the radar system. It reflects the echo strength of the system under different pulse widths and ensures consistent signal processing results under different pulses.

[0071] Next, the value calculated using the radar constant is substituted into the dBz0 calculation formula to obtain the dBz0 values ​​corresponding to the long, medium, and short pulses. The dBz0 value represents the initial value of the radar reflectivity factor. By analyzing the dBz0 under different pulse widths, the difference between long, medium, and short pulses can be obtained. These differences are key information needed in the subsequent splicing process to ensure that the radar reflectivity factor can be adjusted accurately under different pulse conditions.

[0072] Then, when calculating the radar reflectivity factor dBz, the dBz0 values ​​of the medium pulse and the long pulse are added to the dBz0 of the short pulse, and the difference between each pulse and the short pulse is added. The adjusted dBz value can make the reflectivity factors of different pulse widths consistent, thus avoiding the inconsistency caused by different pulse widths. This step ensures that the radar can accurately estimate the target reflectivity factor at different distances.

[0073] Finally, the radar software selects the corresponding radial data for splicing based on the positions of the splicing points of different pulses. Through this splicing method, a complete radial data is formed. This data eliminates the influence of the pulse ring, making the radar detection process more accurate and reliable, especially when switching between long, medium and short pulses, to ensure that the radar's observation accuracy is not affected. This process is crucial for the refined observation of weather radars and ensures the continuity and stability of the multi-pulse radar system.

[0074] The following are two specific industrial application examples of the all-solid-state weather radar combined pulse ring elimination method:

[0075] Example 1: Application in Airport Weather Radar

[0076] In the airport's weather monitoring system, real-time and accurate precipitation, wind speed and wind direction information is crucial to the safety of aircraft takeoff and landing. This all-solid-state weather radar can obtain long-range, medium-range and short-range atmospheric reflectivity factors in real time through a three-pulse combined pulse ring elimination method, eliminating the loop effect between different pulses. Airport radars need to ensure accurate meteorological data within a wider detection range. This method can ensure that the radar spliced ​​data is seamlessly connected in long, medium and short pulse modes, avoiding data discontinuity or measurement deviation problems caused by pulse switching. Finally, complete radial data is formed, which effectively improves the monitoring accuracy of key meteorological elements such as precipitation intensity and wind speed, and ensures the airport's early warning and emergency response to sudden severe weather.

[0077] Example 2: Application in wind farm meteorological monitoring

[0078] The operation and maintenance safety of wind farms is highly dependent on accurate weather forecasts, especially the precise monitoring of sudden storms and precipitation. The all-solid-state weather radar system can be installed around the wind farm to monitor meteorological data such as precipitation, wind speed and cloud height in real time. In a wind farm, due to the large height variations of the wind rotors, the radar needs to detect meteorological conditions at different distances. By applying the combined pulse ring elimination method of three pulses, the radar can seamlessly monitor meteorological conditions from close to long distances, especially in environments with turbulent airflow or heavy precipitation, to ensure the accuracy of the data. Through accurate weather monitoring, wind farms can optimize wind turbine operation strategies to avoid equipment damage or energy loss in severe weather, thereby improving the operational efficiency and safety of wind farms.
