摘　　要：对巡航导弹3个主要辐射源：蒙皮、尾喷管及羽流进行了深入分析，建立了巡航导弹红外辐射计算模型．此外，在红外辐射的大气传输理论基础上，综合考虑高度、倾斜及气象条件等各种因素，分析了大气衰减对红外辐射的影响，建立了大气透过率的理论模型与计算方法．最后，以某型号巡航导弹为例，利用此模型计算了3—5μm和8—12μm两个波段的红外辐射强度、大气光谱透过率和平均透过率，以及经过大气衰减后的红外辐射强度，并对计算结果进行了分析．结果表明，这是一种计算巡航导弹红外辐射的简单方法．Three primary radiant points of the cruise missile, i.e. fuselage, hot spot and plume were analyzed, and an infrared radiation calculation model of cruise missile was established. Secondly, synthetically considering various factors such as height, slope and weather conditions, the influence of atmospheric attenua- tion was analyzed based on the theory of atmospheric transmission of the infrared radiation, and an theoretic model and calculation method of the atmospheric transmittance were established. Finally, take a certain cruise missile for example, the infrared radiation in 3 ~ 5 p,m and 8 ~ 12 p,m were computed based on the computing model. The atmospheric spectral transmittance and average transmittance and the infrared radiation attenuated were also calculated. An analysis of the results was also given. The results indicate that this is a simple method to calculate the infrared radiation of the cruice missile.
