弹道修正弹追踪制导律研究

A Study on Pursuit Guidance Law of Trajectory Correction Projectiles

文中对速度追踪制导律和弹体追踪制导律的工作原理进行了研究,利用六自由度弹道仿真程序对弹道修正弹两种追踪方式下的末段修正弹道和脱靶量进行了对比计算,研究了两种追踪方式下激光探测器光轴的轨迹及激光探测器空间视场在地面投影区域的变化;弹体追踪方式命中精度虽然较低,但由于工程实现简单、成本低,仍有其工程使用价值。

This paper describes the basic principle of velocity pursuit guidance law and body pursuit guidance law of trajectory correction projectiles, researches the terminal correction trajectory and miss distance under pursuit guidance laws by 6—DOF trajectory simulation program, researches the orbit of laser detector ray axis and ground projection area of laser detector spatial viewpoint. For body pursuit guidance law, although there is less hit precision, nevertheless it is simple in hardware implementation and low cost, so it's also valuable in engineering.
