| 摘 要： | 固体火箭发动机排气羽流对红外制导信号的衰减研究,对红外信号的探测与制导具有重要的理论和应用价值。文中主要介绍了红外制导信号的衰减机理,提出了计算排气羽流红外制导信号衰减的有效方法,编制了计算软件DROP,用该软件计算了水雾及颗粒群的光谱透射比,并与SIRRM软件的计算数据进行了对比。结果表明,两者数据基本一致,在工程应用中具有较大的参考价值。

| Abstract: | The research on infrared signal attenuation caused by solid motor exhaust plume is very important to detection and guidance of infrared signal.The attenuation mechanism of IR signal was mainly introduced,and the effective method for calculating infrared signal attenuation was put forward,then DROP software was programmed.The ratio of spectrum transmission of water drop and solid particle cluster was calculated by means of the DROP software,and the results were compared with calculation data of SIRRM software.The results show that two kinds of data are consistent,which can provide reference to engineering application. |
