空间直接碰撞末制导总体设计与侧向控制力选择

System Design for Terminal Homing and Option for Lateral Acceleration of a Space Interceptor

本文是空间直接碰撞拦截器末制导研究的一部分，其目的是确立空间栏截器末制导总体设计的正确思路，降低各分系统研制难度。文章在分析了末制导系统设计的基本矛盾和以往设计存在问题之后，提出解决问题的新思路，即紧紧围绕着大侧向过载修偏并实现高精度制导与控制的思想，系统地设计了末制导的方法，并从总体优化角度证明了采用大侧向力修偏的合理性，由此表明新的设计思想在研究中的重要性。

System design for teminal homing of a space direct hitting interceptor is a part of the terminal homing researeh and it is discussed in the paper.A correct design idea is determined in the research project.Firstly,the basic contradication and problem are analysed.Secondly,an idea to solve them is put forward,that is,the guidance and control rules in terminal homing are redesigned by using the larger lateral acceleration control(LLAC)to correct a cross range error(CRE).Then,the reasonableness and benefit through using LLAC are discussed on the principle of system optimization so that the importance of the new idea is proved.
