基于外测弹道数据的后效误差分析及折合

Analysis and Conversion of After-effect Error Using Trajectory Data

本文提出了一种利用外测弹道数据特性判断后效段时间,进行后效误差分析的方法.在后效误差分析的基础上,将试验外测弹道后效段速度参数的变化量从发射坐标系转换到弹体系下,直接转化为折合弹道的速度变化量,由此可进行后效误差折合.

After estimation of the after-effect time using tracking measurement trajectory data, a method is proposed to analyze after-effect error. Based on this, an effective after-effect error conversion method is also proposed. Then, dispersion of after-effect phase in test tracking measurement trajectory is transferred from launch coordinates into missile coordinates, thus facilitating trajectory conversion.
