光-能谱集成技术系统及其地质应用

本文阐述了遥感、物探、地质等多地学数据的综合应用技术和方法。作者从多源遥感数据在铀资源勘查中的应用特点出发,充分利用了铀矿地质的特色信息--航空放射性伽玛能谱(航放)信息,进行了信息融合,开发多光谱遥感、雷达遥感、高光谱遥感、航放四种信息融合的MR、MSR、HSR融合图像。在此基础上,将融合图像的解译成果与重力、磁力、地化、地质等其他地学信息进行复合分析,从而建立了具核工业特色的光-能谱集成技术系统。利用该系统在植被覆盖的花岗岩、火山岩和沉积盆地地区进行了地质填图和铀矿找矿应用,取得了很好的应用效果。

Integrated Technologic System of Remote Sensing Spectrum and Airborne Radioactive Gamma Energy Spectrum and its Application

A comprehensive application technology and method for various geo-scientific data like remote sensing, geo-physics, geology, etc. were discussed in this paper. From the application characteristics of multi-source remote sensing data in uranium resource exploration, the authors made researches on information fusion by taking the full advantage of aero-radioactivity gamma information, the characteristic information in uranium geologic field, and developed three types of fusion images of MR (Multi- spectrum-Radioactivity), MSR(Multispectrum-Synthetic aperture radarsat-Radioactivity), and HSR(Hyper-spectrum-Synthetic aperture radarsat-Radioactivity) based on four kinds of information of multi-spectrum remote sensing, synthetic aperture radar, hyper-spectrum and aero-radioactivity. On the basis of the above researches, the authors further overlapped the interpretation map of the above fusion images with other geo-scientific data like gravity, magnetic, geo-chemical, geological and so on. As a result, an integrated technologic system with characteristics of nuclear industry, based on remote sensing spectrum and airborne radioactive gamma energy spectrum, was established. The system has been used to geological mapping and uranium deposit exploration in vegetable-covered granite area, volcanic rock area and sediment basin. Good application effects were obtained.
