Paper Abstract

With a certain space-based low earth orbit satellite as its detecting target, after the author did a lot of research work and by experiential speculation, the paper initially gives simplified framework, shape and size of the satellite. Based on the different kinds of heat-control materials adopted by the satellite, the concerned material parameters were given out, such as emissivity, heat capacity, density and thermal conductivity etc. Based on the satellite's geometrical features, its 3D model was established via 3DS Max and was translated to customized-format model file which can be easily read-out by vc-program. The orbit of the satellite is a sun-synchronous orbit, its attitude control system was carried out by means of inertial directionality. According to the temperature of the surface given by a certain institute, the temperature of the satellite surface in the whole orbit period was gained by linear interpolation method. The infrared radiation model of the satellite was established based on the temperature and features of the proper materials. The motion model was established by two-body orbit motion formula which was based on the six orbital elements. At last, the infrared simulating images are provided under the system parameters such as detecting positions and detecting wavebands etc. The infrared scene simulation of space object can be achieved by this method and the base for the infrared detection of the space object is established.
