The Infrared Signature of a Moving Targets Based on Atmospheric Propagation Modeling

在建立目标热模型的基础上 ,考虑了红外辐射的大气吸收模型 ,进而提出了在动态目标红外仿真中大气透射率的计算方法。利用计算机实现了汽车的三维造型 ,汽车表面红外辐射的计算 ,大气衰减量的计算 ,得到了经过大气衰减的红外模拟热像。

Based on the thermal model of a target, the atmospheric propagation model of infrared radiation is discussed in this paper. Then, the method of calculating the atmospheric transmission rate is presented. Using solid modeling technique on computer, the infrared radiation, then the atmospheric transmission rate of a car is calculated. As a result, the infrared image including atmosphere transmission is obtained.
