为了提高机动车载跟瞄发射系统的瞄准精度,提出在其发射光路中引入快速反射镜来修正发射激光的方向。研究了快速反射镜激光指向修正量和粗红外跟踪脱靶量以及反射镜空间实时绝对角度的关系,结合激光发射光路和红外跟踪光路的结构特点,提出了将船摇坐标变换理论应用到快速反射镜激光指向修正量的解算中。建立了快速反射镜激光指向修正量与粗红外跟踪、快速反射镜空间位置的关系,并通过MATLAB编写了M函数,建立了SIMLINK仿真模型。基于仿真模型得出了激光指向修正量与快速反射镜转角的关系数据以及在快速反射镜工作范围(± 6’)内的简化公式。试验结果表明:该解算算法正确,解算精度较高,最大静态解算误差为2.9";载车在三级公路上以20 km/h的速度跑车时,激光指向的控制精度为方位角11.65"、俯仰角15.38",均满足项目指标要求。
To improve the tracking and pointing accuracy of the laser shoot system for a mobile vehicle
a two-dimensional fast steering mirror was induced to the shooting system to correct the direction of laser beam. The relationship between the correction values of laser beam pointing of the fast steering mirror and the miss value of laser tracking as well absolute angles of the mirror in space was investigated. On the basis of the characteristics of laser shoot system and infrared tracking system
the ship-swaying coordinate transformation theory was applied to solution of the correcting values of the laser beam directing and the MATLAB was used to write the M-function and establish the SIMLINK model. The simulated result educes the related data between the laser direction correction value and the fast-reflector angle and a simple formula in the ±6' working range of the fast steering mirror. The experiment results indicate that arithmetic solution is correct
and the max static state error is 2.9"
showing a higher precision. This arithmetic solution has been applied to control of the laser directing of the mobile armored car weapon equipment and its dynamic precision is the azimuth angle of 11.65"
the pitch angle of 15.38"
which satisfies the project needs.
