D-InSAR技术及其在活断层运动学研究中的应用

D-InSAR Technology and Its Application to Kinematics Research on Active Faults

D-InSAR技术作为InSAR观测的重要方面,可以对地表形变进行比较精确的探测。随着目前国内外利用InSAR观测技术对地形测绘、活断裂(主要是活断层发育地区的地震同震形变)、地面沉降、滑坡、火山爆发、冰川运动等所进行的一系列探索和实践,该技术的研究也开始从萌芽向更加广泛和纵深发展。本文在介绍InSAR技术基本原理的同时,重点介绍目前该项技术在活断裂运动学研究中的应用以及未来的研究展望。

DInSAR is an important part of InSAR observation With DInSAR observation the precise crustal deformation can be obtained As employed in the reserch on terrain mapping, active faults kinematics (especially on coseismic deformation), land subsidence, landslide, volcano eruption, glacier motion, InSAR will be used in more extensive field As the basic theory is depicted, this paper mainly focuses in how to use InSAR in the research on the active faults and its prospect
