本文介绍一种新的寻的导弹的制导规律.这种设计概念是以最短寻的时间为基础的.业已表明,为了实现这种制导概念,需要有一种算法和一个制导指令产生器,这种算法能够预测相遇航向;这种制导指令产生器能使导弹的飞行方向转向预测的相遇航向.本文推导出了相遇航向的预测算法,而且还证明该整个的制导规律是很容易实现的.为了验证最短的时间特性和扩大的发射范围,本文还给出了仿真结果. This paper presents a new guidance law for missile seekers, which is based on the shortest seeking time.It has been shown that in order to realize such a guidance concept, an algorithm and a guidance order generator are needed The algorithm can predict the course of the encounter, and the guidance command generator can turn the missile’s flight direction to the predicted encounter course.This paper deduces the prediction algorithm of the encounter course, and also proves that the entire guidance law is very easy to achieve.In order to verify The shortest time characteristics and the extended emission range, the simulation results are also given in this paper.
