摘　　要：首先建立卫星温度场的理论计算模型;然后给出利用辐射传递因子求解卫星表面间自身辐射和空间热流多次散射的计算方法和流程;最后计算分析了卫星表面间自身辐射和空间热流多次散射对自身表面温度及3～6μm和6～16μm两个波段红外辐射特征的影响。研究结果对于提高空间目标红外辐射特性的计算精度以及空间目标的红外探测与识别具有参考价值。Firstly, the theoretical calculation models of the satellite＇ s temperature field are established. Secondly, the calculation method and procedure of the satellite＇ s surface scattering is introduced with the use of the radiative trans- fer factor. Finally, the influence of the satellite＇ s surface scattering on the surface temperature and the infrared feature in 3 ~ 6 μm band and in 6 ~ 16 μm band is calculated and analyzed. The research results of this paper have referential value for the calculation precision of infrared feature, infrared detecting and recognition of spatial targets.
