摘　　要：雷达差分干涉测量技术(D-INSAR)是一种目前较为先进的地表形变监测方法。在监测地表微小形变方面,D-INSAR与常规方法相比有着显而易见的优势。它不仅能以厘米量级甚至更小尺度监测地表形变,且能对大面积测区进行快速的监测,极大的推进了地表形变遥感应用领域的研究。本试验选取一矿区影像数据,应用D-INSAR技术对该影像进行二轨法差分干涉处理,从而得到该矿区的主要形变区域,结果表明了该方法在山区矿山开采沉陷范围监测的可行性并提出几点改进方法。D-INSAR is a relatively advanced method of surface deformation monitoring. D-INSAR has obvious advantages over conventional methods in monitoring small surface deformations. It can not only monitor the surface deformation on the order of centimeters or even smaller scales, but also can quickly monitor large-area measurement areas, which greatly promotes the research on the application of surface deformation remote sensing. In this experiment, the image data of a mining area is selected, and the D-INSAR technology is used to perform two-track differential interference processing on the image to obtain the main deformation area of the mining area. The results show the feasibility of this method for monitoring the mining subsidence area in mountainous areas and several improvements are proposed.
