摘    要:飞机蒙皮对于背景辐射的反射可以作为红外目标识别的辐射源,但背景辐射通常来源于太阳辐射和地面背景辐射等辐射的综合作用,其复杂性和多变性也可能使飞机的红外反射辐射严重干扰红外制导的准确性,因此,研究复杂环境背景下的飞机蒙皮红外反射特性对于红外目标识别和红外导弹制导等应用具有重要意义.本文基于Schlick双向反射分布函数(...

关 键 词:红外反射特性  飞机  背景辐射  双向反射分布函数  辐射遮挡因子

Abstract:The reflection of aircraft skin to background radiation can be used as the radiation source of infrared target recognition,but the background radiation usually comes from the combined effect of solar radiation and ground background radiation,and its complexity and variability may also make the infrared reflection radiation of aircraft seriously interfere with the accuracy of infrared guidance.Therefore,it is of great significance for infrared target recognition and infrared missile guidance to study the infrared reflection characteristics of aircraft skin in complex environment.In this paper,based on the Schlick bidirectional reflectance distribution function(BRDF)model,combined with the finite element method,the radiation shielding factor is calculated by the reverse Monte Carlo method,the atmospheric spectral transmittance is calculated in the MODTRAN software environment,and the infrared reflectance and radiation characteristics of aircraft under different conditions are studied.The results show that different detection angle and detection band have great influence on the infrared reflection characteristics of the aircraft,and the reflection radiation of the aircraft skin has the characteristics of non-uniform distribution.
Keywords:infrared reflection characteristics  aircraft  background radiation  bidirectional reflection distribution function  radiation occlusion factor
