Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle testing, and in particular to an array type high energy laser counter-unmanned aerial vehicle testing method and device. Background Art

[0002] In recent years, drone countermeasures have become an important issue facing academia and engineering. High-power laser weapons have the advantages of low cost and rapid strike, and have gradually gained attention in the field of drone countermeasures. When using high-energy lasers to ablate drone structures, it is necessary to ensure that the laser reaches a certain energy density per unit area to achieve the purpose of ablation.

[0003] Based on the needs of long-range target tracking, laser weapons need to be combined with radar or optical image tracking equipment, and the target point determined by tracking is generally the strike center point of the high-energy laser. Although the image recognition system can track the target of the UAV, it will cause unclear imaging when facing a small-sized UAV at a long distance. At the same time, when a single-beam laser design is adopted, due to unclear image tracking, it is difficult for a single-beam laser to accurately hit a specific part of the UAV, which can easily cause inaccurate strikes. In order to make up for the shortcomings of image tracking equipment, it is necessary to develop laser equipment with a larger strike range. Arrayed high-energy lasers composed of multiple high-energy lasers can solve the problem of inaccurate strikes, but the more high-energy lasers there are, the higher the cost. Therefore, it is necessary to analyze the mechanism of arrayed high-energy lasers striking UAVs through experiments to optimize the structure of arrayed high-energy lasers and reduce costs while ensuring strike efficiency.

[0004] Therefore, it is necessary to design an array high-energy laser counter-UAV test method. Summary of the invention

[0005] The purpose of the present invention is to solve at least one of the technical problems existing in the prior art and to provide an array-type high-energy laser counter-UAV test method and device.

[0006] To achieve the above object, the technical solution adopted by the present invention is as follows: a method for testing an array high-energy laser to counter UAV, comprising the following steps:

[0007] Step 1, prepare a test device and a UAV; the test device includes a high-energy laser array assembly, an automatic rotating pan-tilt platform, a high-speed camera, an infrared camera, and a laser sight; the high-energy laser array assembly includes a carrier box and a plurality of high-power lasers; the plurality of high-power lasers are arranged in parallel in the carrier box to form a laser array; the laser array is used to emit a high-power laser beam to the UAV to ablate the UAV; the automatic rotating pan-tilt platform is used to drive the carrier box to rotate to adjust the emission direction of the high-power laser beam; the high-speed camera is used to capture images of the test process; the infrared camera is used to capture a heat distribution diagram of the UAV when it is ablated; and the laser sight is used to emit a sighting laser parallel to the high-power laser beam to detect the UAV;

[0008] Step 2, conducting a laser countermeasure UAV test; turning on the automatic rotating gimbal, high-speed camera, infrared camera, and laser sight, remotely controlling the UAV to fly into the test area, and when the laser sight detects the UAV, remotely controlling the laser array to emit a high-power laser beam to the UAV to ablate the UAV;

[0009] Step 3, observe the ablation process and analyze the morphology of the ablated UAV, and obtain the radius and depth of the ablation area of ​​the tested UAV;

[0010] Step 4, perform finite element simulation on the test process to obtain the radius and depth of the simulated UAV ablation area;

[0011] Step 5: Compare the radius and ablation depth of the UAV ablation area obtained by simulation and experiment, adjust the finite element simulation parameters to make the simulation results consistent with the experimental results, and derive the ablation depth-time variation curve of the key points of the simulated ablation area.

[0012] Furthermore, in step 1, the high-energy laser array assembly further includes a plurality of water-cooled radiators, and the water-cooled radiators are used to dissipate heat from the high-power lasers.

[0013] Furthermore, in step 3, observing the ablation process specifically includes:

[0014] Based on the images taken by the high-speed camera, the process from the drone being irradiated by the high-energy laser array to its fall is recorded to obtain the key time parameter t b and t u ;

[0015] Among them, t b is the total time from the start of laser ablation to the start of the rapid fall of the drone; t u It is the time from when the laser starts ablation to when the UAV starts to experience an unbalanced state of rolling, tilting and spinning.

[0016] Furthermore, in step 3, analyzing the morphology of the ablated drone specifically includes:

[0017] Analyze the images taken by the high-speed camera to observe whether multiple parts of the drone are ablated and the distribution of the ablated parts;

[0018] The microscopic morphology of the ablated parts of the drone was observed under an optical microscope, and the ablation degrees of different parts were compared. The area with the highest ablation degree was defined as the core ablation area, the remaining areas with low ablation degrees were defined as secondary ablation areas, and the areas without ablation were defined as intact areas.

[0034]

[0035] Where i is the identity matrix;

[0036] When solving the q parameter numerically, there will be multiple solutions. The rule for selecting the solution is: the solution that makes the square of the half-width of the beam positive should be selected;

[0037] After finding the q parameter, separate its real and imaginary parts, which correspond to the beam waist position and beam waist radius of the light beam respectively; use the ABCD law to find the beam parameters of the Gaussian beam after the optical system transformation, and thus obtain the beam waist position and beam waist radius after the beam transmission transformation;

[0038] Find q -1 After the parameters are determined, the real part and the imaginary part are separated. The real part and the imaginary part correspond to the curvature radius of the phase surface and the spot radius of the light beam respectively. The beam parameters of the Gaussian beam after the optical system transformation are calculated by using the ABCD law, so as to obtain the curvature radius of the phase surface and the spot radius after the light beam transmission transformation.

[0040] The high-energy laser array assembly includes a carrier box and a plurality of high-power lasers, wherein the plurality of high-power lasers are arranged in parallel in the carrier box to form a laser array, and the laser array is used to emit a high-power laser beam to the drone to ablate the drone;

[0041] The automatic rotating platform is arranged at the bottom of the carrying box, and is used to drive the carrying box to rotate so as to adjust the emission direction of the high-power laser beam;
