摘　　要：滑坡是频发的破坏性极强的自然灾害,运用合成孔径雷达干涉测量和差分干涉测量技术对滑坡进行研究是近年来国际遥感界的一个研究热点。介绍InSAR和D-InSAR的基本原理和数据处理流程,及近十年来欧洲(主要是法国、意大利、瑞士等国)、加拿大和日本等国学者运用此技术在滑坡灾害调查、动态监测以及空间分析与灾害预测等方面的研究成果,结果表明虽然目前InSAR技术具有一定的局限性,但随着新的技术方法和高空间分辨率数据的大量出现,其运用于滑坡研究具有广阔的前景。总结从数据源、数据处理软件和数据处理人员三个方面中国所面临的挑战。The application of InSAR on landslide research is becoming a focus topic in the domain of international remote sensing, because landslide is a kind of devastating, frequently, worldwide natural disaster. The principle and data processing flow of InSAR and Differential InSAR is introduced in brief firstly. Then the studies of its application on landslide detecting, monitoring, spatial analysis and forecasting made by scholars from several＇representative country such as France, Italy, Switzerland, Canada and Japan for the past 10 years are reviewed in detail, the limitation and the prospect of the application of InSAR on landslide research are analyzed. Finally the gap between oversea and China is summarized at last.
