利用DORIS软件进行SAR差分干涉测量提取地震形变研究
|
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-InSAR) 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 Bam earthquake.
