崩滑流雷达遥感应用潜力分析

综述了我国崩滑流（崩塌、滑坡、泥石流）遥感的应用现状；着重分析了成像雷达遥感在崩滑流识别、监测、预警中具有的独特优势，特别是随着新型成像雷达遥感（极化、干涉雷达）的发展，基于干涉雷达发展的差分干涉测量技术能以一量级甚至更小尺度测量地表形变，在崩滑流研究中能提供定量的动态信息，为崩滑流遥感应用研究注入了新的活力，开辟了新的思路；并指出以雷达（ＳＡＲ）遥感信息为主的多源信息复合解译，能为崩滑流灾害的调查提供更为方便、准确、及时、动态的信息．

Potentialities analysis of radar remote sensing application to landslides

In this paper, the status quo of remote sensing application to collapse, landslides and debris flow is overviewed. The emphasis is laid on the unique capability of radar remote sensing, especially due to the development of new imaging radar technologies such as Po1SAR and InSAR. Interferometry radar-based SAR differential interferometry can measure the terrain deformation of the order of centimeter or millimeters and provide dynamic informations about collapse, landslides, and debris flow to monitor, predict and mitigate these geological hazards.
