本文概述了弹道式导弹惯性平台自对准原理,解决了利用平台罗经原理在以重力惯性坐标系为对准基准时出现的方位控制信号消隐现象,从而提出转换方位控制的全方位自对准方案。在推导全方位自对准系统失准角方程式基础上,对系统的对准误差进行了分析,从而找出影响系统对准精度的主要误差源。最后分析了对准误差对导弹射击精度的影响,并据此提出惯性器件精度的基本要求。
This paper summarizes the self-alignment principle of ballistic missile inertial platform and solves the phenomenon of azimuth control signal blanking when using gravity principle. Program. Based on the derivation of the equation of misalignment angle of omni-directional self-alignment system, the alignment error of the system is analyzed to find out the main error sources that affect the alignment accuracy of the system. Finally, the influence of alignment error on missile firing accuracy is analyzed, and the basic requirements of inertial device accuracy are proposed accordingly.
