【摘要】：随着人们对大尺度地形信息与地表环境变化监测需求的提升,以及哨兵1号(Sentinel-1A)、大地2号(ALOS-2)等合成孔径雷达(synthetic aperture radar,SAR)卫星的宽幅模式数据不断获取,宽幅雷达干涉测量(SAR interferometry,InSAR)技术已成为大尺度地形测绘、地球动力学(地震、火山、滑坡等)与人工地物结构健康监测等领域的研究热点。分析了两类宽幅SAR数据,即扫描(ScanningSAR,ScanSAR)模式与逐行扫描地形观测(terrain observation by progressive scans SAR,TOPSAR)模式开展干涉测量的主要限制条件与解决方法,探讨了宽幅InSAR形变监测关键误差估计与改正方法、时间序列分析技术与方位向位移观测技术,并给出2008年矩震级Mw 7.1新疆于田地震同震、震后形变监测应用。随着宽幅SAR数据的不断积累,宽幅InSAR大地测量学有望得到深入发展与应用。
[Abstract]:With the increasing demand for monitoring of large scale terrain information and surface environment changes, as well as the wide amplitude mode data of the synthetic aperture radar (SAR) satellite, such as the sentinel 1 (Sentinel-1A), the ALOS-2 (ALOS-2) and other synthetic aperture radar (radar, SAR) satellites, the broadband radar dry measurement (SAR interferometry, InSAR) technology has become a large scale terrain. Surveying, geodynamics (earthquakes, volcanoes, landslides, etc.) and artificial ground health monitoring and other fields, two types of wide amplitude SAR data, namely, scanning (ScanningSAR, ScanSAR) mode and progressive scanning terrain observation (terrain observation by progressive scans SAR, TOPSAR), are analyzed in this paper. The key error estimation and correction method of wide amplitude InSAR deformation monitoring, time series analysis technology and azimuth displacement observation technology are discussed, and the same earthquake of moment magnitude Mw 7.1 in Xinjiang Yutian earthquake in 2008 and the application of post earthquake deformation monitoring are given. With the no accumulation of wide amplitude SAR data, broad amplitude InSAR geodesy is expected to be further deepened. Development and application.
