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.
