SAR图像处理方法及在干旱地区找水工作中的应用

SAR IMAGE PROCESSING AND IT'S APPLICATION IN WATER RESOURCE EXPLORATION WITHIN ARID AREA

以内蒙古阿拉善左旗地区为例 ,介绍了RadarsatSAR图像在干旱地区找水中的应用方法 ,包括SAR图像的正射校正及与TM图像的融合处理 ,同时简要介绍了应用效果。

The application of SAR remote sensing image becomes wider. Because it can penetrate to a certain depth into ground, and is very sensitive to water content, so it's more powerful than other remote sensing methods in water exploration in arid area. This paper takes the area of Alashanzuoqi in Inner Mongolia as an example, introduces the application method of water resource exploration with SAR images, including orthgraph correction, fusing with TM image and its application result in brief.
