摘要
对飞机目标3个辐射源蒙皮、尾焰及尾喷管进行了深入分析,建立了视线方向飞机红外辐射计算模型,并综合考虑大气衰减的主要因素,分析了大气衰减对红外辐射的影响,给出了一种大气透过率的计算方法。最后以3～5μm波段为例,计算了某飞机的红外辐射强度、大气透过率和经过衰减后的飞机红外辐射强度。
The algorithm of infrared signature of aeroplane along the line of sight is studied.Three infrared radiation sources of the aeroplane are researched： skin,spout and plume.The model of infrared signature of aeroplane along the line of sight is proposed.According to the propagation of infrared radiation in atmosphere,the attenuation effects of atmosphere absorbing,dispersion and meteorological attenuation are analyzed,then a calculation method for the propagation in atmosphere is introduced.Finally an example of the calculation model is given.
