助推段反导的动能拦截弹导引律设计

为降低需用过载，对助推段反导的空基动能拦截弹导引律进行分析研究。在建立导引系统模型的基础上，增加修正因子，分析碰撞拦截点处的过载需求；区分有无预测拦截点距离误差的情况，仿真分析了拦截弹道和过载动态响应。仿真结果表明，该导引律能降低需用过载，实现碰撞拦截。

Guidance Law Design for Kinetic Interceptor for Antimissile in Boost P hase

In order to decrease the required overload, the air?based kinetic interceptor?s guidance law for boost phase anti?missile was analyzed and researched. The navigation guidance system model and correction factor were proposed to analyze the required overload at the impact intercept point. Distinguishing the situations with or without the distance error of predicted intercept point, the interception trajectory and the overload dynamic response were analyzed and simulated. The simulation results showed that, the guidance law can reduce the available overload and accomplish interception and collision.
