The anti-sniping control method of the unmanned vehicle laser anti-sniping system specifically comprises the following steps:
(1) before the laser anti-sniper system of the unmanned vehicle works, the light beam emitted by the laser emission system and the optical axis of the sighting system are calibrated, so that the laser beam and the sighting line are consistent in access; firstly, setting a reference point with a certain distance from a fixed base station, setting a fixed target at the reference point to mark the reference point, wherein the target center mark of the fixed target is the reference point, measuring the distance between a light outlet of a system and a target center by using a distance measuring machine of a photoelectric observation system, then irradiating laser on the reference point by using a laser emission system to ensure that the optical axis of the emitted laser can be aligned with the target center of the reference point, observing and recording the offset (y, z) between the aiming sight lines of the fixed target center and a visible light camera in a visible light visual field displayed by a display screen of a control system, simultaneously recording the target distance x and the focusing magnification n of the visible light camera, converting the target distance and the focusing magnification of the visible light camera, carrying out the same recording operation, repeating the operation for a plurality of times, and obtaining the relationship between the offset (y, z) of a target plane and the target distance x and the magnification n, recording the relationship of the parameters to obtain a database of the relationship y (f (x, n), and z (f (x, n)), completing calibration, and when the anti-sniping system works, after aiming and locking a target person and a photoelectric reconnaissance device thereof in the control system, the control system can adjust the offset (y, z) according to the parameter target distance x and the value of the focusing magnification n, so that a sight of the aiming system falls on the intersection point of the laser optical axis and the target;
(2) after the unmanned vehicle moving platform reaches a preset area, the control system 1 horizontally adjusts the two-axis servo turntable, firstly, the vertical gyroscope 5 monitors the motion and attitude information of the two-axis servo turntable, and sends the monitored pitching and horizontal direction information to the control system 1, the control system 1 adjusts a driving motor of the two-axis servo turntable by using the pitching and horizontal direction, horizontal angle correction is carried out in the vertical direction and the horizontal direction until the two-axis servo turntable is in the horizontal state in the vertical gravity direction, so that an emission beam adjusting system and an observing and aiming system of the laser emission system are in the horizontal state, and horizontal adjustment is finished;

The viewing system comprises a high visibility mode and a low visibility mode, and the mode selection is specifically operated as follows: firstly, determining the illumination condition and the air quality of a working environment through an illuminometer and a pm2.5 detector of a photoelectric observation system 9, automatically judging the visual distance of human eyes through the illumination intensity and the air quality, and switching the working mode of an observing and aiming system to realize the optimal working state; when the illumination is good and the visual distance is good, the observing and aiming system works in a high visual mode, and a visible light camera capable of focusing is used for shooting target information and an infrared observation instrument is used for shooting the state of light beam spots; when the observation and aiming system works in a low-visibility mode under the condition of weak light, smoke dust or sand blown by wind, the states of the target and the light beam are observed by using the infrared observation instrument.
In order to achieve the function of the laser beam, the laser beam is required to continuously cover the target, so that the diameter of the beam at the position of the target has a minimum requirement. In order to achieve the desired effect, the emitted light beam adjusting system 8 is designed to have a focal length adjustable structure, and the diameter of the laser beam can be adjusted to a desired value according to targets of different sizes and different positions. There is a need for a method of calculating the minimum spot diameter of a beam: the minimum laser beam diameter is (response time of the system + network delay) multiplied by the target movement speed + (angular precision of rotation of the two-axis servo turntable + angular precision of emitted beam calibration + angular precision of leveling) multiplied by the distance from the target to the turntable. The response time of the system is within 70ms, the network delay is within 30ms, the rotating angle precision of the rotary table is better than 0.2mrad, the leveling angle precision is 0.2mrad, and the calibration precision of the emitted light beam is better than 0.2 mrad. Assuming that the moving speed of the object is 0.5m/s and the distance is 500m, the minimum diameter of the beam thus calculated is 0.35m, corresponding to a divergence of the emitted beam of 0.7 mrad. The design control system can send commands in real time according to the target position to control the emitted light beam adjusting system to carry out focusing, and the divergence angle of the light beam is optimized. The system operator can adjust the spot size and the divergence angle of the emitted light beam with reference to the calculation result.
