摘要
针对合成孔径雷达差分干涉测量(D-InSAR)技术无法准确提取矿区大梯度地表形变信息这一问题,提出了一种融合水准数据的D-InSAR矿区全尺度梯度地表形变监测方法(Differential Interferometry Synthetic Aperture Radar Method Based on Leveling Data Fusion,LEV-InSAR),并以山西省长治市霍尔辛赫矿区3501工作面作为试验区域,以9景哨兵1号影像和部分同时期水准数据作为研究数据,采用LEV-InSAR模型对该区的地表形变进行了监测。试验结果表明:LEV-InSAR模型监测结果与观测线水准实测结果基本吻合,累计下沉误差最大为41 mm,其倾向线和走向线水准观测点均方根误差分别为10.2 mm和14.9 mm,平均相对误差分别为14.4%和26.6%。LEV-InSAR模型在一定程度上恢复了研究区内大梯度形变区域的形变量,实现了矿区全尺度梯度地表形变监测,验证了该监测方法的可行性和适用性。
Aiming at the problem that differential synthetic aperture radar interferometry(D-InSAR)technology can′t accurately obtain large gradient surface deformation information in mining area,this paper proposes a D-InSAR full-scale gradient subsidence monitoring method(Differential Interferometry Synthetic Aperture Radar Method Based on Leveling Data Fusion,LEV-InSAR)based on leveling data fusion.The 3501 working face of Holxinhe Mining Area in Changzhi City of Shanxi Province was taken as the test area,9 sentinel-1 images and part of leveling data of the same period were taken as the study data,the LEV-InSAR model was used to monitor the surface deformation in the study area.The study results show that the monitoring results of LEV-InSAR model are basically consistent with the measured results of the observation line leveling,the maximum accumulated subsidence error is 41 mm.The root mean square error of the leveling observation points of the dip line and the strike line is 10.2 mm and 14.9 mm,respectively,and the average relative error is 14.4%and 26.6%,respectively.The LEV-InSAR model can restore the value of the large gradient deformation area in the study area to a certain extent,and realize the full-scale gradient surface deformation monitoring in the mining area,the feasibility and applicability of the monitoring method are verified.
