摘　　要：合成孔径雷达差分干涉测量技术(Differential Interferometry Synthetic Aperture Radar,D-InSAR)已成为监测矿区地表沉降的有力工具之一。文章选取2景2004-12-26—2005-01-30覆盖济宁矿区的C波段的ENVISAT ASAR影像作为干涉对,首先对整景影像进行差分干涉处理,得到D-InSAR一系列结果图,然后选取沉降明显的葛亭矿区进行精细化研究,结合GIS软件叠加数字正射影像图DOM、开采平面图和矿区边界图等进行空间分析。结果表明:双轨D-InSAR技术可以对矿区的沉降分布进行有效的探测与定位,且能对矿区的沉降程度进行监测。D-InSAR is one of the useful techniques for monitoring the ground subsidence. Two C-land ENVISAT ASAR images from December 26th,2004 to January 30th,2005 were selected as interferometry pair. First of all,the total image were processed and a series of maps were obtained, then the DOM, mining plan and mining boundary map in Geting mining area were performed for the spatial analysis in GIS. The results show that the technology of double-track D-InSAR can be used to effectively detect and locate the subsidence distribution in the mining area,and monitor the degree of sub-sidence in the mining area.
