摘要
阐述合成孔径雷达差分干涉测量(D-InSAR)技术原理和方法,采用二轨法获取西山矿区地表形变信息。通过ARCGIS软件显示形变图,并提取角反射器处形变值,与GPS实测结果一致。验证了高分辨率TerraSAR-X影像监测矿区地表沉降的可行性。
In this paper,the principle and method of the synthetic aperture radar differential interferometry（D-InSAR） are described firstly,the surface deformation information caused by underground coal mining has been observed in the Xishan Mine Area.The deformation maps are displayed by the ARCGIS software,and the deformation value of corner reflectors can be extracted,which is consistent with the value from GPS.It verifies the feasibility of the high-resolution TerraSAR-X images in monitoring the surface subsidence caused by underground coal mining.
