摘要
论述了对TDICCD相机安装精度导致调制传递函数(MTF)下降的机理,定量分析了TDICCD相机安装精度对MTF的影响程度,并分析了TDICCD相机安装精度与卫星飞行姿态的耦合效应对MTF的影响。文章的分析方法,可为合理确定TDICCD相机的安装精度指标提供理论分析的依据。
This paper is aiming at analysis of the MTF degradation mechanism caused by the assembly precision of TDICCD camera. Specifically, by considering the satellite attitude image shift mechanism introduced by the assembly precision, the influence on modulation transfer function (MTF) is detailed discussed. The results show that the analysis can provide a basis for setting reasonable specification of assembly precision of TDICCD camera.
