由于矿区地表形变而导致建筑物的裂损甚至发生坍塌等事故已经成为制约区域环境、社会经济可持续发展的地质灾害之一.本文介绍一种基于PS-InSAR技术检测矿区地表三维形变的方法,利用长时间序列SAR影像上保持相对稳定的永久散射体点分析时间序列上相位变化,来提取矿区地表形变信息,以便更好地预防和避免地质灾害问题.%The mining area surface deformation causing the cracks and even collapse of buildings has become one of the geological disasters that restrict the sustainable development of regional environment and social economy. This paper introduces a detection method of 3D deformation of mine surface based on PS-InSAR technology,analyzes the phase variation in time series by using the Persistent Scatterer keeping relative stable in a long time series SAR images, to extract the mine surface deformation information, so as to prevent and avoid geological disasters.
