空间光学遥感器外遮光罩的地球反照辐射的随机模拟计算

Random Simulant Calculation of the Earth-reflectionfor Outer Barfle or Space Optical Remote Sensor

根据概率论的基本原理，用随机模拟法对空间光学遥感器外这光罩的地球反照辐射进行了计算，有效地模拟了任意空间位置的阳光反照的定向辐射强度分布。此方法尤其适用于空间飞行器外露腔体的精确热计算。

According to the probability theory, the radiation of the earth-reflection in complexcavity has been calculated by random simulant method in this paper. The distribution of thedirectional radiant intensity of the earth-reflection in orbits has been effectively simulated.This method especially applies to the accurate thermal calculation for the outer cavities ofspacecraft.
