在轨太阳能帆板红外特征是大多数卫星红外特征最主要的组成部分, 它的研究对于卫星红外探测和识别具有重要意义。从轨道热流的计算出发, 对在轨太阳能帆板的红外辐射特征进行了完整的建模。在此模型基础上, 选择一定参数, 以某轨道为例, 分别计算了太阳能帆板的表面温度特征和红外特征, 并进行了对比和分析, 结果表明卫星太阳能帆板反射太阳和地球等环境的红外辐射比较微弱, 其红外特征主要取决于其自身温度引起的红外辐射。

The research on infrared feature of the solar panels in orbit, which is the main part of most satellites infrared feature, is of great significant in satellite infrared detection and recognition. In this paper, firstly the calculation model of infrared feature of the solar panels in orbit is completely established based on the calculation of orbital heat flux. Secondly, on the basis of this model and with some chosen parameters, the surface temperature and infrared feature of the solar panels on a certain orbit are calculated respectively. Thirdly, through the contrast and analysis, results indicate that the solar panels infrared radiation feature depends mainly on their self-emitted radiation caused by their temperature, and the reflection infrared radiation from the sun and the earth and environment is faint.
