SUBSIDENCE MEASUREMENT WITH PS-INSAR TECHNIQUES IN SHANGHAI URBAN
DInSAR PS-InSAR Subsidence Measurement Urban
2015/12/30
Spaceborne SAR Differential interferometry (DInSAR) has been used to monitor some geological disasters such as ground subsidence. This paper applies two Permanent Scatterer InSAR(PS-InSAR) techniques ...

Ground subsidence monitoring over Jiaxing region,Zhejiang province from 2006 to 2010 using time series InSAR technique
Ground subsidence InSAR time series Jiaxing
2015/7/27
Because of over-exploration of groundwater for a long time, Jiaxing region, northeast of Zhejiang province has suffering serious ground subsidence during the past several decades. In this paper, we in...
本文从GNSS、InSAR、重力、水准等多种大地测量资料联合确定活动断层地壳形变、应变和应力，以及与GIS相结合的角度出发，讨论了基于库仑破裂准则的活动断层地震危险性评估方法，系统阐述了活动断层地震危险性评估系统的设计。该系统主要利用各种大地测量数据联合确定活动断层区域的位移场，反演计算应变场、应力场、活动断层运动参数以及库仑应力；通过确定活动断层的临界应力值，建立地震危险性评估模型，评估可能发生...
一种机载双天线InSAR系统干涉参数定标新方法
合成孔径雷达干涉测量 外定标 基线 相位偏置 高程控制点
2010/5/4
干涉参数定标对于机载双天线InSAR（Interferometric Synthetic Aperture Radar）系统的大面积高精度数字高程模型（DEM，Digital Elevation Model）获取具有重要意义。为了高效地进行干涉参数定标，本文从双天线InSAR获取DEM的基本原理出发，构建了一种新的考虑干涉相位偏置、基线长度和基线水平角三个干涉参数的外定标模型，设计了外定标模型的未...
