对空间碎片温度特性的分析,是利用红外传感器探测空间碎片的基础,也是研究航天器在轨安全的重要内容。文章对空间碎片接收不同辐射进行全面分析,研究其在轨运行情况,建立热平衡方程,完成对不同时刻其温度变化的计算,并绘制出温度变化曲线。结果表明空间碎片在轨道上不同位置有不同的红外辐射特性。该研究对利用天基空间探测器进行空间碎片的检测、识别,以及航天器的规避有参考意义。
The analysis of the temperature characteristics of the space debris is the basis for using infrared sensors to detect the space debris and is also an important content for studying the on-orbit safety of the spacecraft. In this paper, a comprehensive analysis of the different radiation received by space debris is carried out, the on-orbit operation of the space debris is studied, the heat balance equation is established, the temperature variation at different times is calculated, and the temperature variation curve is drawn. The results show that space debris have different infrared radiation characteristics at different locations on the orbit. The research is of reference significance for the detection and identification of space debris using space-based space probes and the avoidance of spacecraft.
