摘　　要：仿真试验中,目标辐射特性计算精度影响红外成像设备作用距离的测试精度,反射辐射是目标辐射特性的重要组成部分,针对空中目标的反射辐射特性进行建模并给出了工程计算方法,该方法考虑了空中目标反射天空背景辐射、反射太阳直射辐射、反射地面背景辐射。针对某空中目标进行了理论计算,并与实测数据进行了对比,结果表明该方法精度较高。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.
