摘要
D-InSAR技术作为20世纪90年代发展起来的新型空间对地观测技术,凭借着全天候、全天时、高分辨率和连续空间覆盖的特点到了广泛的应用。本文以内蒙古营盘壕煤矿为研究区,利用Sentinel-1A数据,通过二轨差分干涉测量方法得到该矿区的沉降数据。通过对沉降数据进行各种GIS分析获取工作面上方的地表沉降信息,并将D-InSAR沉降数据与GPS沉降数据进行精度验证,证明了D-InSAR技术在矿区地面沉降监测的可行性。
D-InSAR technology,as a new space to earth observation technology developed in the 1990s,has been widely used with the characteristics of all-weather,all-weather,high-resolution and continuous space coverage.In this paper,yingpanhao coal mine in Inner Mongolia is taken as the research area,and the settlement data of the mining area is obtained by using sentinel-1a data and two track differential interferometry.Through various GIS analysis of the settlement data,the surface settlement information above the working face is obtained,and the accuracy of D-InSAR settlement data is verified by GPS settlement data,which proves the feasibility of D-InSAR technology in land subsidence monitoring of mining area.
