摘要
介绍了一种沿视线方向巡航导弹辐射强度的计算方法,全面分析了影响红外辐射特性的各种因素,包括巡航导弹(蒙皮、发动机热部件和尾焰)自身发射和蒙皮反射背景(太阳、天空或地球)的红外辐射;强调了不能忽略背景辐射的影响,并在俯仰角的计算中考虑了地球曲率的影响;使用LOWTRAN7计算红外辐射通过大气传输的衰减,最后给出了计算结果。
An algorithm of infrared signature of cruise missile along the line of sight is proposed. Both the emitted target radiance and the reflected background signature are analysed in the calculation of infrared intensity. The importance of the reflected back- ground signature is emphasized in this paper. The earth curvature is considered in the calculation of the elevation. Atmospheric transmission is generated by the software of LOWTRAN7. An example target signatures generated using the proposed methodology is presented at the last.
