Abstract：We use Sentinel-1A data from July 2017 to April 2019 to monitor and analyze the landslide deformation rate and displacement time series in the area of Ahai power station, and evaluate the reliability of SBAS-InSAR monitoring results using GPS data in the same period. The results show that the landslide deformation gradually increases from the rear edge to the front edge of the slope during the InSAR observation time, with the maximum annual deformation rate of 136.7 mm/a and the maximum cumulative deformation of 216 mm. The SBAS-InSAR result is relatively close to the measured GPS data in the area with small deformation and has high accuracy. However, in the area with a large deformation gradient, there are still some differences between SBAS-InSAR and measured GPS data.
