| 摘 要： | 从分析ETM各波段图像的信息特征入手,在黄土覆盖等环境因素干扰严重的地区,利用遥感技术对其铀矿化的信息进行了提取.在ERDAS软件的支持下,应用图像融合、波段比值、主成分分析、光谱指数等技术方法,对ETM遥感影像数据进行增强处理.其中,图像融合与传统的图像融合略有不同,是在进行图像融合前将原始图像（ETM1～5,7）进行低通滤波处理,使得融合后的图像既保留高分辨率数据的空间信息,又保留低分辨率数据的光谱信息.在对研究区的遥感数据进行增强处理后,选取有利波段组合,圈定了有利铀成矿的远景区.

| Abstract: | Starting from the analysis on the image information at various ETM wave bands in this paper, favorable uranium mineralization is extracted by remote sensing technology in an area seriously disturbed by such environmental factors as loess overlay. Supported by the ERDAS 8.5 software , ETM remote sensing image data are enhanced with the methods such as image fusion,wave band ratio , major composition analysis, spectrum index. Among them, image fuse is slightly different with traditional image fuse. The primitive images (ETM1~5,7)are carried out low-pass before they are carried out image fuse. The fused images have space information of high-resolution data and spectrum information of the low resolution data. After remote sensing image data are enhanced, the author chooses to find avail wave band combination and the prospective areas of uranium orebody. |
