基于三轨法D-InSAR技术的矿区地面形变分析
|
摘要
采用三轨法D-InSAR干涉处理6景覆盖济宁某矿区ENVISAT ASAR数据,分别提取了含有地形信息的DEM、增强干涉图以及相对应的相干图、地面形变图;对这些成果文件进行后处理,分别获取了不同时段的矿区地面沉降量、沉降值和沉降面积,并对这些结果进行初步分析;最后选择矿区已有的部分水准点监测结果和三轨法D-InSAR监测结果进行比较。同时,初步讨论和分析了水准监测结果和三轨法D-InSAR监测结果存在差异的主要原因,从而展示了三轨法D-InSAR技术在矿区地面形变监测中的应用。
The DEM containing topographic information,enhanced differential interferograms,corresponding coherence and maps of mining ground deformation are extracted by processing six ENVISAT ASAR data covering a mine of Jining by three-pass D-InSAR.Then,mine ground subsidence is analyzed in the light of distribution of mining subsidence and statistics of subsidence area;finally,the accuracy analysis is executed by the way of comparing some level of monitoring result with the monitoring results from three-pass D-InSAR.The difference of the two monitoring results is shown,at the same time,main reason of it is discussed and analyzed preliminarily.The application of three-pass D-InSAR monitoring ground deformation of mining area is shown.
