空中目标红外特性的计算方法

摘要

The physical model of IR signature of an aerial tar get is constructed. The computational method of the IR intensity and contrast in tensity of the target is discussed. The compact of the background radiation, inc luding the sun, the sky and the earth, and the atmospheric attenuation to the in frared radiation is considered. LOWTRAN7 code is used to calculate solar radiati on, atmospheric radiation and transmission.%文中建立了空中目标红外特性的物理模型,讨论了目标红外辐射强度和对比强度的计算方法,考虑了太阳、天空、地面等背景辐射和大气的衰减作用对目标红外辐射的影响.本文应用了LOWTRAN7软件计算太阳辐射、大气辐射和大气透过率等参数.
