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。
This paper is a part of the research on the guidance of space direct collision interceptor final guidance. The purpose of this paper is to establish the correct thinking of the end guidance overall design of space column cutters and to reduce the difficulty of developing each subsystem. After analyzing the basic contradictions of the design of the final guidance system and the existing problems in the past design, the article proposes a new way to solve the problem, that is, the idea of tightly controlling the large lateral overloading and implementing high precision guidance and control is designed systematically End guidance method, and from the overall optimization point of view to prove the rationale for the use of large lateral force deflection, which shows that the new design ideas in the study of importance.
