摘要
介绍了一种沿视线方向飞机红外特性的计算方法。所采甩的飞机模型简单实用,有助于分析飞机沿视线方向的投影面积。在辐射强度计算中本文不仅考虑了蒙皮、尾喷管和尾焰的红外辐射特性,还考虑了太阳、天空、地球背景辐射和大气的衰减作用对飞机红外辐射的影响。
The algorithm of infrared signature of aeroplane along the line of sight is introduced. The aeroplane model is simple, helping to get the projective area of aeroplane along the line of sight. In the calculation of infrared intensity, not only infrared radiation sources including skin, spout and plume are considered, but also the effects on the infrared radiation exerted by the background radiation of the sun, the Sky, the earth and the atmospheric attenuation are considered.
