针对目标机动能否逃脱导弹攻击的判断问题,根据比例导引法弹目相对运动方程组分析了目标机动逃脱导弹攻击的条件,推导了目标法向过载与导弹最大需用过载间的关系,建立了目标机动导致比例导引导弹脱靶判别的数学模型,运用该模型对算例进行了仿真与分析,仿真结果符合机动逃脱的运动学一般规律,说明该模型可以用于对抗仿真系统中飞机能否机动逃脱的判据。

In view of the issue of whether target maneuver can survive missile attack, according to the movement equation set of the proportional guidance missile, the conditions of target maneuver surviving missile attack was analyzed. The relations between the normal overload of the target and the maximal requisite overload of the missile were deduced, and the model of the missdistance was given. Based on the analysis of the simulation results, the model could be used in counterwork simulation of the battle plane and the missile.
