Abstract

The infrared radiation change of the solar panels is an obvious feature to tell whether they are working normally or not. In this paper, the calculation model of the satellite's solar panels infrared feature is established. First, combined with the parameter descriptions of the satellite's six orbital elements and with the use of the coordinate transformation method, the calculation formulas of the radiation flux that the solar panels get from the sun and the earth are derived, no matter which location of the satellite in orbit. Second, the calculation model of the solar panels' temperature field is established, and the equations are solved numerically with the boundary condition of radiation heat flux. Finally, the calculation models of the solar panels' infrared radiation in 3~5μm band and 8~14μm band are established, and the equations are solved numerically, thinking differently about their radiation and reflected radiation.
