摘要： 利用时间序列技术（TS-InSAR）对Sentinel-1A卫星2015年12月12日至2018年5月30日覆盖珠江三角洲地区的影像进行处理，反演出广州、佛山与东莞的地面变形信息.研究结果表明，研究期间广佛地区与东莞地区整体平稳，局部发生沉降，沉降点主要集中在工厂密集处与工程施工处，并对沉降原因进行了初步分析.证明了利用Sentinel-1A来监测珠江三角洲地面变形情况也可以取得良好效果.

关键词: 地面沉降, 永久散射体, 地下水, 广佛地区

Abstract: Time-series InSAR (TS-InSAR) technology is used to process the images of the Sentinel-1A satellite covering the Pearl River Delta region from December 12, 2015 to May 30, 2018, and invert the ground deformation information of Guangzhou, Foshan and Dongguan. The research results show that during the research period, the Guang-Fo area and Dongguan area were stable and partially settled. The settlement points were mainly concentrated in the densely populated areas of the factory and construction sites, and the reasons for the settlement were analyzed. It is proved that using Sentinel-1A to monitor the ground deformation in the Pearl River Delta can also achieve good results.

Key words: ground subsidence, persistent scatterer interferometry, groundwater, Guang-Fo area
