@@@@The calculation precision of target radiation characteristic affects the test precision of IR imaging equipments’ operating distance in the simulation tests. The infrared reflected radiation is an important component of infrared radiation characteristic. In this paper, the modeling of infrared reflected radiation and the engineering arithmetic are presented. The infrared reflected radiation came from the solar, the sky and the earth is calculated. According to the contrast of calculating data and test data from the same air-target, the result shows that the precision of this arithmetic is accurate.
