二连盆地西部SAR影像与TM影像复合处理及其地质应用

SAR AND TM DATA FUSION FOR WEST ER-LIAN BASIN AND ITS GEOLOGICAL INTERPRETATION

摘要: 针对SAR与TM数据的不同特征,研究了SAR与TM影像的几何校正方法及波谱信息复合方法,将SAR影像与复合图像进行比较,并且分别用SAR图像和复合图像对内蒙二连盆地进行地质解译,发现雷达图像能够较好地反映沙漠覆盖区的隐伏构造信息,而TM与SAR的复合图像能够较好地发挥两种数据的优势,拓宽了遥感的波段范围,对于图像解译和实际应用都有重要的意义。

Abstract: Considering difference between SAR and TM data,a method for geometric correction and merging for SAR and TM images is investigated.While conducting interpretation for Er-Lian basin of Inner-Mongolia,comparing the SAR images and merged TM/SAR images,the later can reveal more information and is helpful for image interpretation.The data fusion can expand the bandwidth of the remote sensing as well.
