卫星红外特征的研究对于卫星红外探测与识别以及卫星红外隐身设计都具有重要意义。论文首先计算了卫星的轨道辐射热流，接着计算了卫星各个表面的温度随轨道运行周期的变化，在此基础上计算了卫星各表面的自身辐射的红外辐射以及反射环境的红外辐射，由此建立了计算卫星红外周期性特征的数理模型，并以某轨道上六面体卫星为例，数值计算了卫星六个不同表面在中红外和远红外两个大气窗口的周期性红外辐射特征，相关结果可为卫星红外探测识别以及红外隐身设计提供参考数据。

The research on infrared radiance characterization of the satellite is of great significance in satellite infrared detection and recognition and the satellite infrared stealth design. In this paper, firstly, the radiant heat flux of satellite was calculated. Secondly, each surface temperature changed with orbit cycle was calculated. On this basis, the self-emitted infrared radiation and its reflecting infrared radiation from the environment of the various satellite surfaces were calculated, thus a mathematical model to calculate the satellite infrared radiant periodic characteristics was established. Finally, taking a hexahedron satellite in an orbit for instance, the radiant luminance of MIR and FIR in atmospheric window and its change with time on its body's six different surfaces during the period on the orbit were calculated. Results can provide the reference for satellite infrared detection and infrared stealth design.
