摘　　要：选取山东省某矿区6景Sentinel-1A SAR影像,以SRTM DEM为辅助高程数据,分别采用全分辨率与多视法DInSAR对影像进行处理,获取矿区地面沉降信息;收集该矿区同时期5个工作面开采信息和4条水准观测线上水准监测的地面沉降信息进行精度的验证与对比分析.结果表明,全分辨率与多视法DInSAR监测得到的矿区地面沉降的分布、形态和变化趋势与矿区工作面的开采情况相符.全分辨率DInSAR监测得到的地面沉降最大值与多视法DInSAR监测的地面沉降最大值没有较大差异,并未明显提高多视法DInSAR监测大梯度地面沉降的能力.Selecting six sentinel-1A SAR images of a mining area and taking SRTM DEM as auxiliary elevation data,this paper uses full-resolution and multi-look DInSAR to process the images,respectively,and obtain the ground subsidence information of the mining area.This paper also collects the mining information of five working faces and the ground subsidence information of leveling monitoring on four leveling observation lines in the mining area at the same time to verify make the accuracy verification and comparative analysis.The results show that the distribution,shape and change trend of ground subsidence in the mining area monitored by full-resolution and multi-look DInSAR are consistent with the mining situation of the working faces in the mining area.The maximum value of ground subsidence monitored by full-resolution DInSAR is not significant different from that of monitored by multi-look DInSAR,which does not significantly improve the ability of multi-look DInSAR to monitor large gradient ground subsidence in the mining area.
