Abstract：Sentinel-1A is a new generation SAR satellite on orbit. Its TOPS imaging mode is wide imaging mode, which can realize large-scale surface deformation monitoring. There are very rare researches on SBAS processing based on TOPS model images published in China and abroad at present. With the Yellow River Delta as the study area, 27 Sentinel-1A TOPS mode images from May 2015 to April 2016 were selected to generate 94 pairs of interferograms. Then, ECMWF meteorological data were used to estimate the atmospheric delay, which could achieve a wide range of atmospheric phase correction. Finally, the deformation and deformation velocity of the study area were extracted by SBAS timing analysis method. The results show that there is still a continuous settlement in recent years, and there is a significant sedimentation funnel in the vicinity of Qicheng industrial park, Guangrao saltworks and Nanzhaike Village in Guangrao Town. The results of settlement monitoring are consistent with the settlement rules described in the study area, and this proves the feasibility and effectiveness of TOPS model SBAS timing analysis method applied to deformation monitoring.
