摘要
用Ｍｏｎｔｅ—Ｃａｒｌｏ法对空间光学遥感器的大口径光学窗口的地球红外辐射进行了分析和模拟计算。考虑了光线在外遮光罩挡光环内的多次漫反射和在光学窗口表面的镜反射，讨论了目前普遍采用的挡光环等效面假设的局限性。
The earth infrared radiation is analysed and calculated for the large aperture optical window of high resolution space optical remote senser by Monte-Carlo method .The multi-scatter in baffles and direct reflection in the surface of the optical window are considered,and thelimitation of vane structural assumption is also discussed.
