摘　　要：针对空间目标红外特性复杂、难以直接通过试验获取等问题,提出了空间目标红外特性仿真分析方法。以天宫一号(TG-1)为研究对象,首先从理论上分析空间目标的红外辐射特性和温度特性;然后根据已经获取的TG-1结构参数对目标进行构型反设计,以蒙特卡洛方法为计算基础,仿真出TG-1在空间轨道上不同位置处的轨道热流和温度;通过对仿真结果数据的处理,得出TG-1在空间轨道不同位置处的红外特性差异,总结出典型空间目标红外特性的一般化规律,为空间目标红外探测和识别提供重要的理论支撑。Space target infrared characteristics are complex and difficult to be obtained by experiments directly. Aiming at these problems, a method of simulation analysis on space target infrared characteristics is proposed. Tian Gong-1(TG-1) is taken as the object of study. Infrared radiation characteristic and temperature characteristic are analyzed theoretically at first. Then TG-1 is redesigned according to its available structure parameters. Simulation for the orbit heat flux and temperature of TG-1 on different positions of space orbit is processed based on Monte Carlo method. By processing the result data of the simulation,the differences of infrared characteristics on different positions of the space orbit are obtained and the basic rules of typical space target infrared characteristics are summarized to form the essential theory support for the detection and recognition.
