高光谱侦察技术的发展

Development status of hyperspectral reconnaissance

在高空间分辨率成像条件下,高光谱成像具有获取景物每个像元光谱细微差别的能力。通过对光谱特性的定量分析,实现对真假目标、目标和伪装物、覆盖物与周围正常环境之间的光谱特征微弱变化的检测并确定目标位置,已成为侦察的一种新型重要手段。对国外高光谱侦察技术在伪装目标、地雷、近海水下探测的应用研究及相关试验进展进行了总结,展望了高光谱侦察技术的发展趋势。

Under the condition of high spatial resolution imaging, hyperspectral imaging has the ability to abtain subtle spectral differences of each pixel of the scene. By analyzing hyperspectral image quantitatively, spectral characteristics faint variation can be detected for real and false target, camouflaged target, different soil coverings and background, so that the target can be located. Hyperspectral imaging has become an important method for reconnaissance anti camouflage. The research of detecting camouflaged target, mine, and ocean costal through hyperspectral imaging are summarized, and future trends of hyperspectral imaging on military reconnaissance are discussed.
