导弹助推段天基预警探测综述

鉴于天基探测对国家导弹防御有着重要作用,对天基探测系统的组成及工作方式、红外与光谱的天基探测方法进行总结归纳。首先介绍了天基系统的高轨和低轨卫星的主要任务,并以助推段导弹为目标,对其尾焰进行红外分析与光谱分析。在此基础上,介绍了最大中值滤波、Top-hat滤波、PM滤波等经典的红外探测方法及光谱角信息散度、光谱角匹配、二值编码等的光谱探测(识别)方法,通过对其探测结果的分析,总结出了红外探测与光谱探测的优缺点。

Overview of space-based early warning detection for missile booster

Considering that the space based detection plays an important role in the national missile defense,the composition and working mode of the space-based detection system,the infrared and spectral space-based detection methods are summarized. Firstly,the main tasks of the high earth and low earth orbit satellites in the space-based system are introduced,and the exhaust plume is analyzed by infrared and spectral analysis based on the boost stage missile. On this basis,this paper introduces the infrared detection method of maximum median filtering,Top-hat filtering,PM filtering and spectral information divergence angle of the classic,spectral angle matching,two valued spectral encoding and detection(identification) method,through the analysis of the detection results,summarizes the advantages and disadvantages of infrared detection and spectrum detection.
