星载合成孔径雷达差分干涉测量(D-InSAR)技术在形变监测中的应用概述

本文综述了地球表面形变的主要类型(包括开采沉陷、地表沉降、地壳运动、地震形变、火山运动、冰川运动及山体滑坡等)及其在我国的分布状况，结合合成孔径雷达干涉测量(包括InSAR及D-InSAR，统称InSAR技术)的技术原理及特点，介绍了国内外InSAR技术近年来在形变监测领域的应用与发展。通过与传统形变监测及GPS监测技术的对比后指出，由于InSAR特有的技术特点，使其在各类形变监测应用中具有传统方法无可比拟的技术优势，必将对形变监测的发展起到极大的推动作用。

Monitoring Deformation Using Differential Interferometry Space-borne Synthetic Aperture Radar

In the paper, main deformation types of earth surface (including mining subsidence, ground subsidence, crust movement, earthquake deformation, volcano movement, glacial movement and landslide)and its distribution in China are discussed. Combining InSAR technique (InSAR and D-InSAR) and its characteristics, its application and development of foreign and domestic are introduced in deformation monitoring field in recent years. Finally,the authors put forward that thanks to InSAR technologic characteristics, offering some new methods and means; InSAR is of important technologic advantages comparing with the traditional methods in the deformation monitoring. It is sure that InSAR will promote the developing of deformation monitoring in the future.
