摘要
卫星光学特性包括可见光散射特性和红外辐射特性。文章基于漫反射理论，建模分析了卫星可见光散射强度的空间分布。对卫星本体多层隔热组件和太阳电池阵分别建立温度场模型，计算卫星温度场分布，并分析了卫星红外辐射特性计算方法。根据特定模型的轨道参数和物性参数，数值计算了卫星在本体坐标系卞可见光散射和红外辐射强度的空间分布。
The optical characteristics of the spatial satellite include the characteristics of the visible light and the infrared radiation. In this paper, based on the principle of the diffuse reflection, the space distribution of the satellite visible light scattering intensity is analyzed through the model. The temperature field models of the satellite muhilayer insulation （MLI） and the solar panels are established with the numerical heat transfer, the temperature distribution of the MLI and solar panels are calculated. Meanwhile, the calculation method of the infrared radiation is established. According to the specific satellite＇ s parameters, the spatial distribution of the visible light and the infrared radiation intensity are calculated.
