| 摘 要： | 研究了飞机目标的红外辐射特性,以及红外辐射在大气中的辐射衰减特性.根据现有的理论基础以及飞机自身结构特性,将飞机的红外辐射源分为蒙皮、尾喷口和羽流3部分,并提出了3个辐射源在不同波段、不同角度下的红外辐射特性计算方法.根据红外辐射的大气传输特性,采用了不同波长、不同弹目距离下的大气透过率简易计算方法,并将其与Lowtran7进行比较.计算了飞机在不同波段下,经大气衰减后,最终到达红外探测器的辐射强度.

| Abstract: | The infrared radiation of airplane targets and the radiation attenuation of the infrared radiation in the atmosphere were researched.Based on the existing theoretical study and the structure of the airplane,the infrared radiation sources of the airplane were divided into three categories: fuselage,hot spot and plume.Furthermore,calculation approaches to the character of infrared radiation for the three radiation sources at different wave band and different angle were proposed.According to infrared radiation... |
