摘　　要：为克服传统时序InSAR技术中干涉图获取需要较多计算资源和时间成本问题,利用Hy P3 SAR数据在线服务系统获取哨兵-1号时序干涉图,采用时序InSAR技术对获取干涉图进行分析,得到了2022年3月9日至2022年8月24日间南通港地面形变速率和时序形变。与同期水准观测结果进行比较,平均均方根误差为8.10 mm,证明了InSAR监测结果的可靠。InSAR监测结果显示,南通港由于纳泥、填海和地下水开采导致局地发生形变,但整体地表形变较小,不影响港口正常运行。In order to overcome the problem that more computing resources and time cost are required for the acquisition of interferograms in traditional time-series InSAR technology,this paper uses the HyP3 SAR data online service system to obtain the time-series interferograms of Sentinel-1,and uses time-series InSAR technology to analyze the obtained interferograms,and obtains surface deformation rate and time-series deformation in Nantong port from March 9,2022 to August 24,2022.Compared with the leveling observation results in the same period,the average root mean square error is 8.10 mm,which proves the reliability of the InSAR monitoring results.The InSAR monitoring results show that Nantong port has undergone local deformation due to mud collection,sea reclamation and groundwater exploitation,but the overall surface deformation is small and does not affect the normal operation of the port.
