摘　　要：提出一种基于嫦娥三号着陆器的雷达系统光电偏差检测方法。该方法利用嫦娥三号着陆器与月面图像中特征点之间的相对位置关系获得着陆器在标校电视中的准确位置,再通过计算着陆器与标校电视光轴中心的相对位置关系得到脱靶量,最终获得光电偏差量。试验结果表明,该方法可以有效解决船载雷达系统海上动态检测光电偏差的问题。A method of photoelectric deviation measurement of radar system based on Chang＇ e 3 lander is proposed. The accurate position of the Chang＇ e 3 lander in calibrated television is obtained by using the relative position relationship between the Chang＇ e 3 lander and the characteristic point in the moon surface image. The miss distance of deviation center is obtained by calculating the pixel point range of the lander and the optical axis center, and then the photo-electric deviation is given. The experimental results show that the proposed method can effectively cope with the problem of dynamic photo electric deviation measurement of shipborne radar system on the sea.
