摘要
描述了D-In SAR技术的相关原理,分析了差分干涉测量的整个处理流程,并根据伊朗巴姆地区地震前后的地面形变情况,利用ENVISAT雷达数据,获取了SAR影像的干涉条纹,通过两轨差分干涉测量方法得到实验区域的地面沉降数据,验证了合成孔径雷达差分干涉测量技术在地表变形监测方面的可行性。
The article describes the relevant principles D-In SAR technique,and analyzes the entire process flow differential interferometry measurements. And according to surface deformation Bam earthquake in Iran before and after the use of ENVISAT radar data acquired SAR influence of the interference fringes and using two rail differential interferometry experiments obtained ground subsidence data area. Verify that the differential synthetic aperture radar interferometry technique in measuring the feasibility of surface deformation monitoring applications.
