摘要
介绍了InSAR提取DEM的基本原理,以Earhview InSAR的两种生成DEM数据处理模式处理ENVISAT卫星获取的巴姆地震影像数据,结果分别提取了巴姆地震同震形变场的DEM。对结果进行了对比分析,表明借助外部DEM可以提高提取的地面形变场DEM的精度。
The basic principles of InSAR extracting DEM were introduced,and then DEMS of the Bam earthquake coseismic deformation field were extracted by data processing mode of two generation of Earthview InSAR to DEM processing ENVISAT satellite image date from the Bam earthquake.That the external DEM with high accuracy that could increase the accuracy of the extracted DEM of the ground deformation field was shown by comparison and analysis to the result.
