摘　　要：为了分析飞机过失速机动对拦截导弹带来的挑战,对飞机过失速机动进行了仿真,分析了过失速机动对导弹导引头跟踪的影响。指出"Herbst"机动运动参数变化剧烈,基于匀速直线运动假设来估计飞机位置和速度必将带来较大的误差;当弹目相对距离较小且相对速度较大时,飞机做过失速机动运动,导引头容易丢失目标,通过导引头滤波算法的改进可提高导弹抗目标过失速机动的跟踪能力。To analysis the challenge confronted with missile tracking because of aircraft＇s post-stall maneuvers, the mathematical model of the post-stall maneuvers was given, and simulations were done. Then the effect about post-stall maneuvers on missile guidance system was analyzed. The results of the analysis are： the movement parameters of “Herbst” maneuver vary dramatically, so the position guesstimate is unapt based on stationary movement. The guidance tends to lose target where the aircraft does “Herbst”near missile in relatively high speed. In order to solve the problem of tracking post-stall maneuvering target, fit filter is needed.
