UAVSAR在地表形变监测中的应用综述

A review of UAVSAR application in geological hazard monitoring

针对无人飞行器合成孔径雷达(UAVSAR)差分干涉测量可用于形变监测的发展潜力,介绍了美国UAVSAR的系统设计、工作原理、数据产品等,概述了国内外UAVSAR系统的发展与应用现状、存在问题和发展趋势,重点讨论了UAVSAR在火山、断裂、冰川、冻土、滑坡、地面沉降等典型地表形变监测的应用。其高空间分辨率和较强的穿透性是对星载SAR数据极好的补充,彰显了UAVSAR系统极大的应用前景,为国内机载雷达系统的研究及其在地质灾害监测方面提供参考。

This article first introduces the system design,working principle,data products,etc.of unmanned aerial vehicle synthetic aperture radar(UAVSAR)differential interferometry for deformation monitoring,and then outlines the development and application status,existing problems,and development trends of UAVSAR systems at home and abroad.The article focuses on discussing the application of UAVSAR in typical surface deformation monitoring such as volcanoes,faults,glaciers,permafrost,landslides,and ground subsidence.Its high spatial resolution and strong penetration are excellent supplements to spaceborne SAR data,highlighting the great application prospects of UAVSAR systems,and providing reference for the research of domestic airborne radar systems and their application in geological hazard monitoring.
