摘要
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。
Analysis of the temperature characteristics of space debris is the basis of infrared sensors to detect the space debris, and an important part of the safety study of the spacecraft in orbit. A quantitative analysis of the radiation from space debris is carried out, to study its in-orbit operation. The temperature at different instants is calculated, complete with the temperature vs. time curve. The results show different characteristics at different locations of space debris in orbit. Analysis of the infrared radiation characteristics is important for the space debris detection and identification with space-based probes and for the spacecraft＇s aversion.
