摘要

根据微分几何思想,设计了一种前向追踪拦截转弯制导律。分析了前向追踪拦截制导律的数学模型及其转弯制导的必要条件,从微分几何思想出发,设计了一个辅助圆,只要拦截弹沿着辅助圆飞行,就能满足前向追踪拦截制导律对转弯制导的要求。仿真结果表明,文中制导律设计方法性能较好,简单可行。

Abstract

This paper designs a midcourse guidance law for the head pursuit law. Making an auxiliary circle, which is tangent with interceptor speed and target speed, and the tangent point between the circle and interceptor speed locate in the position of missile. As long as the missile do circular motion along the circle, it will fly to the ahead of target speed direction eventually, meanwhile, the missile speed direction will be in conformity with the target speed direction. The simulation results show that the midcourse guidance law is simple and feasible.

Key words： guidance law; head pursuit; midcourse guidance law; differential geometry
