末端修正迫弹激光探测器及目标方位模型

研究了末段修正迫弹激光探测器的工作原理，对激光探测器修正区域进行了分析，推导了地面坐标系与激光探测器坐标系的坐标变换公式，建立了激光探测器模型；研究了利用目标光斑位置求解目标方位角和跟踪误差角的方法，建立了目标方位模型。仿真计算表明：末段修正时必须选择合适的弹体转速，转速太低会造成对目标的漏扫；通过对末段弹道进行多次修正能够显著提高迫弹的落点精度。本文所建立的激光探测器模型和目标方位模型为末段修正迫弹的弹道模型建立和外弹道仿真计算打下了基础。

Models of Laser Detector and Target Azimuth for Terminal Correction Mortar Projectile

The operational principle of laser detector of terminal correction mortar projectiles(TCMP) was studied, the correction zone of laser detector was analyzed, the coordinate transformation formula between ground coordinate system and laser detector coordinate system was deduced, the target az?imuth model of laser detector was established, and the method of solving target azimuth angle and track error angle was researched by means of target facula. The simulation computation results show that lower body rotation speed may cause the missing of target in the detecting process, hit precision can be greatly improved by using low cost course correction technology. The established laser detector model and target azimuth moael lay the foundation for trajectory model and exterior ballistics simula?tion of TCMP.
