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。
According to the different characteristics of SAR and TM data, the geometric correction method of SAR and TM images and the composite method of spectral information are studied. SAR images and composite images are compared, and the geological images of Erlian Basin in Inner Mongolia are respectively analyzed by SAR images and composite images The results show that the radar image can better reflect the hidden tectonic information in the desert coverage area. However, the composite image of TM and SAR can give full play to the advantages of the two kinds of data and broaden the band range of remote sensing. For image interpretation and practical application All have important meanings.
