摘　　要：文章介绍了航天遥感用的目标与背景全物理仿真系统的组成,试验和计算方法,对多种目标与背景的试验和计算结果进行了比对,证明系统可行,可以用于航天遥感器的仿真。通过建立的物理仿真系统,可以模拟航天光学遥感器在空间摄影的条件,可以选择适宜的成像条件(太阳高度角、观测方位角、观测时刻、相机光学系统参数、接收器参数等);仿真分析CCD相机系统主要参数(光学系统和接收器)是否正确;对各种主要目标与背景完成实验室成像试验。Studying the characteristics of target and background is very important to determining the parameters of the remote sensor and the light condition on satellite. A physical simulation system has been established to study the contrast transfer function (CTF), allowing us to change light condition, camera parameters, such as relative aperture, TDI (Time Delay Integrate) factor, incline angle, and the targets and backgrounds. We have measured the CTF with different target and background, and compared the results with calculated CTF.
