| Abstract: | 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. |
