摘　　要：合成孔径雷达差分干涉测量(D-InSAR)作为一种新型的空间测量技术,具有不受时间和空间的限制、对地物有一定的穿透性等传统测量所不可比拟的特点.它可以探测由地震、火山等引起的地表细微变化信息,精度可达厘米甚至亚厘米级,所以已得到较为广泛的应用.介绍了D-InSAR技术的基本原理,阐述了DOR IS软件进行SAR数据处理的步骤,最后以Bam地震为例提取了地震同震形变干涉图.As a new space geodetic technique, Differential Synthetic Aperture Radar Interferometry （D -In- SAR） have more advantages than traditional geodetic technique such as all - weather, 24 - hour continues surveying and ability to penetrate into substances on the earth . It can survey the slight change of surface deformation which caused by earthquake, volcano etc, and its accuracy can reach centimeter even sub - centimeter and has applied widely. The paper introduces the basic principles of D - InSAR , describes the steps of SAR data processing in DORIS software, and to derive the interferogram of co - seismic deformation by the example of Barn earthquake.
