摘要

使用毫米波雷达导引头的直接碰撞拦截弹在命中前对来袭目标进行成像从而选择关键部位进行打击。在不同的探测角度下,毫米波雷达导引头对目标的成像效果有较大差异,需加以控制。针对直接碰撞拦截弹导引头探测角度的控制问题,在比例导引的基础上进行扩展,设计了探测角度控制末制导律,可实现拦截弹在命中前以期望的角度探测目标,从而保证导引头成像效果。与此同时,考虑导引头最大转角的限制,分析了制导律中探测角的设定范围,进而避免因探测角过大导致导引头丢失目标。最后以数字仿真结果验证了该方法的有效性。

Abstract

Hit-to-kill interceptor uses a millimeter wave radar seeker to image incoming targets before hitting it and select an aim point to strike. At different detection angles, imaging effect of the millimeter wave radar seeker on a target is quite different, which needs to be controlled. Aiming at the problem of detection angle control of the missile seeker on hit-to-kill interceptor, we have extended the proportional guidance and design a final guidance law with detection angle control, which can realize the interceptor to detect a target at a desired angle before hitting, thereby ensuring the imaging effect of the seeker. Meanwhile, considering the maximum steering angle limit of the seeker, we analyze the detection angle setting range of the guidance low and avoid the target loss caused by a too large detection angle. The effectiveness of this method has been verified by digital simulation results.

Key words： hit-to-kill interception; detection angle control; aim point terminal guidance
