飞行器姿态对空间相机像移补偿的影响

为了实现高精度的像移补偿，通过分析飞行器姿态对像移补偿结果的影响，提出空间相机对飞行器姿态精度的要求。首先，根据调制传递函数对像移匹配特性的要求进行分析，确定允许的像移匹配误差。然后，用蒙特卡洛法（即统计试验法）对像移速度误差进行分析和计算。最后，确定满足空间相机像移补偿要求的姿态精度。通过计算得出，满足96级TDI-CCD像移匹配误差要求的飞行器指向精度应优于0.1°，姿态稳定度应优于0.005°/s。方法简单，易于实现，适用于空间相机像移补偿系统的研究。

Effect of aerocraft attitude on image motion compensation of space camerasystem

In order to realize high precision image motion compensation, analyzing the effect on image motion compensation of aerocraft attitude, it may put forward the requirements of space camerasystem. First, to analyse the image motion match character that the modulation transform function of camera requires, and decide permitted errors of image motion matched. Then, the Mento-carlo method (statistic distribution method) is used to analyse and calculate the errors of image motion velocity. Finally, it is decided that the attitude accuracy meets the requirements of image motion compensation.The conclusion can be drawn by calculating, that the requirements of that attitude and the stability of attitude measure accuracy is 0.1°and0.005°/s meet errors of image motion matched of 96 TDI-CCD integration progression. The method is simple and easy to implement, which is suitable for the study of image motion compensation of space camerasystem.
