| 摘 要： | 针对传统形变监测难以在短时间内进行大面积形变监测的问题,结合基于时间序列的雷达差分干涉测量(PS-InSAR)技术,以TerraSAR-X数据为例,重点研究了高分辨率SAR数据在城市地表形变监测中的应用,并对石家庄市、沧州市城区进行了监测,使用了2013年和2014年间各37景数据,采用了SARPROZ软件进行数据处理。实验结果显示,在石家庄市和沧州市各有三处较大形变区域。根据历史水文地质数据资料对比显示,产生形变的区域主要为地下水漏斗区域和大型建筑施工区域。在对石家庄市的分析结果中还发现,由于建筑施工造成了高铁沿线周边区域的较大沉降。此外,经过与沧州市历史沉降资料对比发现,传统沉降区已得到了有效的控制。总体而言,高分辨率SAR影像差分干涉技术为城市大面积地表形变分析提供了一种行之有效的监测手段,对传统沉降区的持续监测、高铁运行、地铁施工建设等具有重要参考意义。

| Abstract: | Aiming at the problem that the traditional deformation monitoring is difficult to monitor the large deformation in a short time,combined with the time-series radar differential interferometry (PS-InSAR),taking the TerraSAR-X data as an example,this paper make the study in the application of surface deformation monitoring in Urban using high resolution SAR data.Experiments were carried out in Shijiazhuang City and Cangzhou City,and the data were processed by using SARPROZ software.The data were processed from 2013 to 2014.37 dataset has been used in each city.The experimental results show that there are three large deformation regions in Shijiazhuang and Cangzhou.According to historical hydrogeological data,the area of deformation is mainly groundwater funnel area and large construction area.In the analysis of Shijiazhuang City,we also found that the area along the high-speed rail has a large deformation due to the construction.In addition,after comparing with the historical deformation data of Cangzhou City,the traditional subsidence area has been effectively controlled.In general,the radar differential interferometry based on high resolution SAR image provides an effective means for monitoring large-scale urban deformation analysis,which is of great reference significance for the continuous monitoring of the traditional subsidence area,high-speed rail operation and subway construction. |
