基于惯导和雷达导引头的再入复合末制导方法研究

对基于惯导系统和雷达导引头的再入复合末制导方法进行了探讨研究。提出了通过利用雷达导引头测量信息 ,估计并修正惯导系统给出的战术弹道导弹再入飞行状态参数偏差 ,然后按其具有终端位置和角度约束的制导律实时进行导引控制的再入复合末制导方法。并通过数学仿真分析验证了方法的可行性。

An approach to reentry compound terminal guidance based on INS and radar seeker

In this paper,an approach to reentry compound terminal guidance is presented,which is based on INS and radar seeker.This method is accordingly brought out by measuring the information via radar seeker,estimating and correcting the errors of flying state parameters from INS on the tactical ballistic missile,and then guiding and controlling the missile in real time under the guidance law with the boundary condition of end position and angle confinement.The feasibility is proved by analysis and simulation.
