突防并命中目标是反舰导弹作战的最终目的,利用雷达方程和反舰导弹自控终点的散布规律,建立了目标舰发现来袭反舰导弹的距离模型和基于发现距离的舰空导弹拦截次数模型,进而建立了以反舰导弹突防概率为目标函数的自导距离寻优模型。仿真显示,寻的雷达自导距离的最优值是存在的,并发现了寻的雷达最优自导距离随反舰导弹速度的增加而减少的规律。

Penetrating and hit the target is the ultimate goal of anti-ship operation. According to radar equation and distribution errors of anti-missile by the end of auto-control, an algorithm of target detecting the incoming anti-ship missile was deduced, and a model of intercepting times was built on target detecting range. Then, the optimizing model of homing radar's auto-guidance range was built on the objective-function of anti-ship missile's penetration probability. The simulation shows that there is the optimum auto-guidance range for a given anti-ship missile as well as target, and it are found that the optimum auto-guidance range decreases with the increase of anti-ship missile speed.
