The analysis of infrared spectrum of space target

Study on infrared radiation spectrum of space targets is valuable for spatial security such as detecting targets, monitoring space fragments, ensuring safety of satellites. The principle of satellite infrared spectrum is discussed, and the infrared spectrum on detectors is simulated, the heat balance equation of space target is given and the temperature distribution of space target is got by node network. According to the Plank principle, the currently calculation method of the infrared radiation luminance of space target is got. The theoretical model of the infrared radiation of the space target is established.
