Study on the Characteristic of IR Radiation from the Target of a Shell Containing the Cone

In this paper, based on the analysis of the thermal environment where the space target embeds and the study of thermal exchanges between the environment and the space target, the mathematics model of the temperature field for the shell containing the cone is built by using the thermal network method, the temperature and the illuminance value in the detector of the target is calculated, the characteristic of the distribution of temperature and IR radiation from the shell containing the cone is discussed in detail.
