摘要: 合成孔径雷达干涉测量技术(InSAR)广泛应用于监测矿区地表形变,采用SAR影像的相位信息可高精度提取试验区的微小形变;但当形变梯度较大,引起干涉影像对的失相干无法得到有效干涉条纹时,则无法获取矿区形变,亟需引入新的技术来解决。本文通过查阅相关文献,分析了目前结合InSAR技术完成矿区大梯度变形监测的几种方法,总结了这几种方法的不足,提出了未来的研究方向和思路。

Abstract: Synthetic aperture radar interferometry (InSAR) technique has been widely used to monitor the ground deformation induced by coal mining and achieve accurately small deformation with the phase information of SAR images in study area.However,the large gradient deformation can't be extracted and several new techniques are introduced to solve when the decorrelation caused by large deformation and the interference fringe can't be effectively achieved.In this paper,several technologies combined with InSAR used to achieve the large gradient deformation induced by coal mining are analyzed and their disadvantages are summarized through the literature.Finally we propose some suggestions about the study in the future.

Key words: InSAR, pixel tracking, mining-induced subsidence model, mining area, large gradient deformation
