摘要

合成孔径雷达差分干涉测量(DInSAR)可用于监测厘米级或更微小的地表形变,以揭示许多物理现象,如地震形变、火山运动、大气变化、冰川漂移、地面沉降以及山体滑坡等。DInSAR作为一种新型的空间对地观测技术,具有不受时间和空间的限制、对地物具有一定的穿透性等传统测量所不可比拟的优势,已得到较为广泛的应用。简要介绍DInSAR技术的基本原理及其处理流程,以Bam地震为例提取Bam地震的同震形变场。
Differential Interferometry Synthetic Aperture Radar(DInSAR) can monitor movements on earth surface at centimeter or even more minute levels.Therefore,many earth physical phenomena can be discovered and analyzed,such as earthquake,volcano,atmosphere meteorology,ice sheet movement,subsidence,landslide,and so on and so forth.As a new space geodetic technique,DInSAR has more advantages than traditional geodetic technique such as all weather,24-hour continues surveying and ability to penetrate into substances on the each.This paper introduces the basic principles of DInSAR and processing flow,and derives the Bam co-seismic deformation by the example of Bam earthquake.
