摘　　要：空间目标的红外辐射特性是对空间目标进行探测与识别的重要依据,也是空间目标红外隐身技术研究的基础。获取空间目标的表面温度场是进行红外辐射特征分析的重要前提。为了确定目标的表面温度场分布,首先建立了空间目标的导热微分方程,求解了其表面温度场分布;然后计算了空间目标的红外辐射强度;最后对国外某型空间目标的表面温度场分布和红外辐射强度分布进行了数值计算并加以分析。计算结果验证了理论分析的正确性,对空间目标的探测具有一定的参考价值。Learning the infrared characteristics of a space target is very important for the detection and identification of the space target and it is also the important basis for the research on infrared stealthy technologies. The surface temperature field of a space target is a precondition to analyze infrared characteristics. To determine the surface temperature field of a target, a thermal conduction differential equation is established and the surface temperature distribution of the space target is dervied. Then, the infrared radiation intensity of the space target is calculated. Finally, the surface temperature distribution and infrared radiation intensity of a given space target are calculated numerically and analyzed. The calculation result verifies the rationality of the theoretical analysis and is of value to the detection of space targets.
