高光谱遥感的发展及其对军事装备的威胁

The Development of Hyperspectral Remote Sensing and Its Threatening to Military Equipments

高光谱遥感融合了光谱分析和成像遥感的优点,可以利用精细光谱特征分析、识别目标的种类和表面状态,给军事装备带来了新的威胁.介绍了高光谱侦察的基本原理和发展概况.分析了高光谱在军事侦察、伪装识别和热红外探测方面的优势,并指出利用植被的光谱特征识别技术可以有效分辨林地背景中的绿色伪装目标;在热红外波段高光谱可以通过探测目标的真实温度和发射率来检测伪装.

Hyperspectral remote sensing has the advantages of spectroscopic analysis and imaging, identifying targets with special spectrum and bringing new threaten to military equipments. The rationale of Hyperspectral remote rensing and the development of instruments are introduced, the advantages of Hyperspectral remote sensing in military detection, camouflage distinguishing and hot infrared detection are analyzed. It is pointed out that the green camouflaged targets on woodland can be found by special spectrum identification. Hyperspectral remote sensing can measure the true temperature and emissivity in hot infrared. The camouflage technique and equipments in existence can not meet the request of hyperspectral remote sensing camouflage.
