Description

Technical Field

[0001] This invention mainly relates to the field of radar cooperative detection technology, and in particular to a method for deploying separate radar transceiver stations for manned and unmanned platforms to conduct radar cooperative detection. Background Technology

[0002] With the development of information technology and automation control technology, an increasing number of unmanned platforms are taking on roles in surveying, firefighting, and rescue, offering advantages such as high mobility and low requirements for the working environment. For example, in the field of surveying, unmanned survey vessels utilize intelligent equipment, which can significantly improve the accuracy of measurements while ensuring the safety of vessel navigation. Unmanned aerial vehicles (UAVs), with their small size, flexible deployment, and low cost, play a vital role in disaster reconnaissance and auxiliary rescue efforts.

[0003] Meanwhile, with the further development of unmanned platforms, they are undertaking an increasing number of tasks. When unmanned platforms perform tasks such as surveying, environmental monitoring, and target detection, they are generally equipped with radar sensors. However, due to limitations in platform size and power supply, the detection capability of a single radar on an unmanned platform is limited, and independent detection by a single platform often cannot maximize its effectiveness. However, by utilizing a manned-unmanned radar cooperative detection system, through a signal-level cooperative detection method where manned platforms transmit and unmanned platforms receive, the detection effectiveness of radar formations can be significantly improved.

[0004] Although radar formation cooperative detection technology has been developing for over a decade, yielding a series of results, related research has mainly focused on signal-level cooperative detection between radars of similar size and point-track-level cooperative detection between radars of different sizes. Research on cooperative detection between radars of different sizes is relatively limited, especially regarding deployment methods and array optimization. With unmanned platform radars joining the formation for cooperative detection, how to combine the parameters of manned and unmanned platform radars to optimize deployment methods, enhance the overall detection capability of the formation, and improve detection capabilities in key directions is a problem that urgently needs to be addressed. Summary of the Invention

[0005] The purpose of this invention is to provide a method for the separate deployment of radar stations for collaborative detection between manned and unmanned platforms. In the process of collaborative detection at the signal level with separate transmission and reception between manned and unmanned platforms, the method of station deployment is studied to improve the collaborative detection efficiency, filling the gap in previous theoretical research and providing support for the efficient performance of collaborative detection between manned and unmanned platforms in the future.

[0006] To achieve the above objectives, the present invention provides a method for manned and unmanned platform radar cooperative detection and transceiver deployment, comprising the following steps:

[0007] Step 1: Set the formation radar position parameters:

[0008] When performing detection missions in key detection directions or areas, the formation radar employs a separate transmission and reception deployment method, with manned platform radar transmitting from the rear and unmanned platform radar receiving from the front, to conduct signal-level coordinated detection. Under this coordinated detection method, the distances of the manned platform radar and the unmanned platform radar from the target are respectively... and The distance between manned and unmanned platforms is , ;

[0009] Step 2: Set the formation radar detection parameters:

[0010] The radar detection capability of a manned platform radar alone is , (1);

[0011] The radar detection capability of an unmanned platform radar when used alone is: , (2);

[0012] The parameters that differ between manned and unmanned platforms include: For the peak transmit power of manned platform radar, For manned platform radar transmission gain, For manned platform radar receiver gain, Peak transmit power of unmanned platform radar For radar transmission gain of unmanned platforms, Increase the radar receiver gain for unmanned platforms;

[0013] The parameters that are the same for manned platform radar and unmanned platform radar are: For the transmit pulse width, For the target cross-sectional area, The wavelength of the emitted pulse. For platform radar detection factors, For platform system wear and tear, The system noise temperature;

[0014] Step 3: Based on the formation radar detection parameter settings in Step 2, under the condition of separate transmission and reception cooperative detection by manned and unmanned platform radars, the radar equation with manned platform radar transmitting later and unmanned platform radar receiving earlier is as follows: (3);

[0015] Step 4: Combining the formula in Step 2, transform the formula in Step 3 into... (4);

[0016] Step 5: Assuming that the single-component transmit power and component arrangement of the manned platform radar and the unmanned platform radar are the same, then the P of the manned platform radar and the unmanned platform radar are...t G t G r The ratios are all equal, so the formula in step 4 can be simplified as follows: (5);

[0017] Step 6: Put As an evaluation function for improving the detection capabilities of formation radar, For performance improvement value;

[0018] When the conditions for separate delivery and receiving stations are met In this case, the detection range of the unmanned platform radar is greater than that of the unmanned platform radar when the transmitting and receiving are separated. The detection efficiency of the manned and unmanned formation radar is improved, and it can be used first when the transmitting and receiving are separated.

[0019] When the conditions for separate delivery and receiving stations are met If the radar receiving range of the unmanned platform is less than or equal to the radar receiving range of the unmanned platform when the transmitting and receiving are separated, but the target can still be effectively detected, then caution should be exercised when deploying the transmitting and receiving stations separately.

[0020] when When there is no real solution, it indicates that the separate transmission and reception system cannot effectively detect the target, and manned and unmanned platform radars cannot cooperate. Therefore, the separate transmission and reception system should be avoided when deploying stations.

[0021] Furthermore, in step 1, when the formation radar performs a detection mission in a key detection direction or detection area, the key detection direction or detection area includes a fixed direction or sector coverage range.

[0022] Furthermore, when the formation radar's primary detection direction is a fixed direction, if there is only one unmanned platform radar, it should be positioned directly in front of the manned platform radar's primary detection direction, with a distance of [missing information]. The relation is (6), of which .

[0023] Furthermore, when the formation radar's primary detection direction is a fixed direction, if there are multiple unmanned platform radars, these radars are arranged in parallel directly in front of the manned platform radar's primary detection direction. The received signals from the unmanned platform radars are then processed using coherent or non-coherent methods to improve the signal-to-noise ratio (SNR), with the SNR improvement value set to D. g Then formula (5) can be transformed into (7) When the focus of detection is a fixed direction, then formula (6) can be transformed into (8).

[0024] Furthermore, when the formation radar's primary detection area is within the sector's coverage area, the unmanned platform radar is deployed at the centerline of the sector, with the spacing between the manned and unmanned platform radars being [missing information]. ;

[0025] If the sector coverage is 2θ, it can be calculated using the cosine theorem. and The relative relationship is substituted into formula (5) for calculation, to obtain... (9).

[0026] Beneficial Effects: This invention provides a method for coordinated detection and transmission / reception deployment of manned and unmanned platform radars. It proposes a method to improve the detection efficiency of manned and unmanned radar formations through deployment strategies. When performing detection missions, this method implements a rear-transmission strategy for manned platform radars and a front-reception strategy for unmanned radars targeting key detection directions. By combining the parameters of both manned and unmanned platform radars, the impact of deployment strategies on the overall detection efficiency of the formation is studied, and criteria for prioritizing, cautiously selecting, and avoiding certain deployment strategies are proposed. This method is applicable to coordinated detection between surface platforms, air platforms, ground platforms, ground-to-air platforms, and sea-to-air platforms. Attached Figure Description

[0036] The preferred mechanism and implementation method of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. For example... Figures 1 to 9 As shown in the figure, this invention discloses a technical solution for a method of deploying separate radar transceivers for manned and unmanned platform radar collaborative detection. Example 1

[0037] A method for coordinated detection and transmission / reception deployment of manned and unmanned platform radars, where manned and unmanned radar formations perform detection tasks in key areas of interest, using a typical scenario such as a maritime platform. Figure 1 As shown.

[0038] 1. When the formation radar is performing detection missions in key detection directions or areas, it employs a signal-level coordinated detection method with the manned platform radar transmitting from the rear and the unmanned radar receiving from the front, thus separating the transmission and reception. Assume that under this coordinated detection method, the distances of the manned and unmanned platform radars from the target are respectively... and The distance between the radars of manned and unmanned platforms is .

[0039] 2. The radar detection capabilities of manned platform radar and unmanned platform radar when detected individually. , They are respectively

[0040] (1);

[0041] (2);

[0042] The parameters in formulas (1) and (2) can be divided into two categories:

[0043] (1) The first category consists of characteristic parameters related to manned and unmanned platform radars, mainly peak transmit power, transmit gain, and receive gain. Specifically, these include the parameters in formula (1). (Peak transmit power of manned platform radar). (Radar transmission gain of manned platforms). (Radar receiver gain of manned platform), in formula (2) (Peak transmission power of unmanned platform radar). (Radar transmission gain of unmanned platforms). (Radar receiver gain for unmanned platforms).

[0044] (2) The second category consists of parameters that are the same between manned and unmanned platform radars. Considering that the transmission and reception are separate, it is a signal-level collaborative detection. The same wavelength, waveform, detection factor, and other parameters are used for transmission and reception. Therefore, the parameters that are kept consistent in formulas (1) and (2) are: (Transmit pulse width) (Target cross-sectional area) (Emitted pulse wavelength) (Some platforms detect factors). In addition... (Platform system losses) and The (system noise temperature) remains basically the same under the same receiving system and operating frequency, and will be set to be the same in subsequent analyses.

[0045] 3. Based on the parameter settings in step 2, the radar equation under the condition of separate radar transceiver cooperative detection for manned and unmanned platforms is as follows:

[0046] (3);

[0047] in , The detection capabilities of manned and unmanned platform radars are as follows: when the radar is transmitted from the rear of the manned platform and received from the front of the unmanned platform. ,in This refers to the distance between manned and unmanned platforms, with the same meaning as in step 1.

[0048] Formula (3) can be transformed into

[0049] (4).

[0050] 4. Assuming that the transmit power of individual components and the component arrangement are the same for manned and unmanned platform radars, the P of manned and unmanned platform radars will be the same. t G t G r Since the ratios are all equal, formula (4) can be simplified as follows: (5).

[0051] 5. When the focus is on a fixed direction, place the unmanned platform directly in front of that direction. The relationship is as follows: ,but (6), of which , The distance between manned and unmanned platform radars.

[0052] 6. Furthermore, based on step 5, when multiple identical unmanned platform radars can be deployed in the foreground, the unmanned platform radars are deployed in parallel in the direction of key concern. Taking a maritime platform as an example, such as... Figure 2 As shown, the received signal is processed through coherent or non-coherent methods to improve the signal-to-noise ratio (SNR), and the SNR improvement value is set to D. g Then formula (5) changes to (7);

[0053] When the focus of detection is a fixed direction, then formula (6) changes to (8), of which .

[0054] 7. Furthermore, based on step 5, when the key detection area is a sector range, the unmanned platform radar is deployed in the middle of the sector range. Taking a maritime platform as an example, for instance... Figure 3 As shown, when the sector coverage is 2θ, the calculation can be performed according to the cosine theorem. and The relative relationship is then substituted into formula (5) for calculation. (9).

[0055] 8. As an evaluation function for improving formation detection capabilities, it is defined as "efficiency improvement value". In formulas (6), (8), and (9) of steps 5, 6, and 7:

[0056] (1) When the site layout conditions are met At this time, the detection range of the unmanned platform under the condition of separate transmission and reception is greater than the detection range of the unmanned platform with a single radar. The detection efficiency of manned and unmanned formations at sea is improved, and it can be used first when deploying stations.

[0057] (2) When the site layout conditions are met At this time, the "receiving detection range of the unmanned platform under the condition of separate transmission and reception" is no greater than the "detection range of the unmanned platform with a single radar", but it can achieve effective target detection. It should be selected with caution when deploying the station.

[0058] (3) When formulas (6), (8), and (9) have no real solutions, i.e. If there are no real solutions, then The absence of a real solution indicates that separate transmission and reception cannot effectively detect targets, and manned and unmanned platform radars cannot coordinate. Therefore, this method should be avoided when deploying such stations. Example 2

[0059] The method of manned and unmanned platform radar collaborative detection and transceiver deployment in this embodiment is basically the same as that in embodiment 1, except that: there is one manned and one unmanned platform radar, which conducts key collaborative detection in a fixed direction.

[0060] 1. Basic Site Deployment Methods: Basic site deployment methods are as follows... Figure 1 As shown, the unmanned platform is moving forward, directly in front of the key detection direction.

Within the analysis range, no situation was found where the transmission and reception could not be carried out in a coordinated detection manner.

[0080] (2) The difference in transmission gain between manned and unmanned platforms is αdB;

[0081] (3) The target detection range of a single radar on an unmanned platform is 200km;

[0082] (4) The benefit of joint processing of the received signals from the two unmanned platforms is 2dB.

[0083] 3. Site layout design:

[0084] Calculate the optimal arrangement parameters for the distance between the two platforms under different α values.

[0085] 4. Site deployment results:

[0086] The analysis range is 0-400km between the two platforms, and the difference in transmit gain between the two platforms is 0-6dB. The results are as follows: Figure 6 As shown, γ increases with the increase of α, and decreases with the increase of ΔL. Within the analysis range, no situation was found where the transmission and reception could not be carried out in a coordinated detection manner.

[0087] Typical, such as Figure 7 As shown, under different α values, the recommended station spacing within a 400km range is as follows:

[0088] When α=1dB, the preferred station spacing should not exceed 115km, and stations should be deployed cautiously within the range of 115-400km.

[0089] When α=2dB, the preferred station spacing should not exceed 195km, and stations should be deployed cautiously in the range of 195-400km.

[0090] When α=3dB, the preferred station spacing should not exceed 305km, and stations should be deployed cautiously within the range of 305-400km.

[0091] When α=4dB, stations can be preferentially deployed in the range of 0-400km;

[0092] When α=5dB, stations can be preferentially deployed in the range of 0-400km;

[0093] When α=6dB, stations can be preferentially deployed in the range of 0-400km. Example 4

[0094] The method of manned and unmanned platform radar cooperative detection and transceiver deployment in this embodiment is basically the same as that in embodiment 1, except that: there is one manned and one unmanned platform radar, which cooperate to detect key sector directions.

[0095] 1. Basic Site Deployment Methods: Basic site deployment methods are as follows... Figure 3 As shown, the unmanned platform is in front, and the unmanned platform radar is deployed at the center point of the sector range.

[0096] 2. Parameter settings:

[0104] The analysis range is 0-400km between the two platforms, and the difference in transmit gain between the two platforms is 0-6dB. The results are as follows: Figure 8 As shown, it can be seen that as α increases, γ increases, and as ΔL increases, γ decreases, and a situation arises where separate transmission and reception collaborative detection cannot be performed.

[0105] Typical, such as Figure 9 As shown, under different α values, the recommended station spacing within a 400km range is as follows:

[0106] When α=1dB, the preferred station spacing should not exceed 55km, and station placement should be cautious in the range of 55-385km, while station placement should be avoided in the range of 385-400km.

[0110] When α=5dB, stations can be preferentially deployed in the range of 0-400km;

[0111] When α=6dB, stations can be preferentially deployed in the range of 0-400km.

[0112] This invention provides a method for coordinated detection and reception of manned and unmanned platform radars using a separate deployment of stations. This method designs the manned platform radar to transmit rear-end and the unmanned platform radar to receive front-end. Combining the parameters of both manned and unmanned platform radars, under typical detection missions, the impact of station deployment on the overall detection effectiveness of the formation is studied, and the ways in which station deployment improves effectiveness are analyzed. Furthermore, a proposed method is presented. As an evaluation function for improved formation detection capabilities, under fixed radar parameters, the indicator of improved manned and unmanned detection effectiveness is that the "detection range received by the unmanned platform in the case of separate transmission and reception" is greater than the "detection range of the unmanned platform with a single radar."

[0113] At the same time, it was proposed that as the distance between manned and unmanned platforms increases, three scenarios will emerge:

[0114] (1) "Unmanned platform receiving detection range under the condition of separate transmission and reception" is greater than "unmanned platform single radar detection range": Under this deployment condition, the detection efficiency of manned and unmanned formations at sea is improved, and it can be given priority when deploying stations;

[0115] (2) The detection range of the unmanned platform under the condition of separate transmission and reception is not greater than the detection range of the unmanned platform single radar, but it can achieve effective target detection: Under this deployment condition, the cooperative detection method of separate transmission and reception can be adopted, and the deployment should be carefully selected;

[0116] (3) Separate transmission and reception means that targets cannot be detected: Under this deployment condition, manned and unmanned platform radars cannot work together, and this should be avoided when deploying the station.

[0117] Furthermore, the analysis and research methods proposed in this invention are universal and applicable to the collaborative detection of sea surface platforms, air platforms, ground platforms, ground-air platforms, and sea-air platforms.

[0118] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
