摘要：
Conventional measurement methods with low spatial resolution, differential interferometric synthetic aperture radar (D-InSAR) is susceptible to signal decorrelation and atmospheric delay, so InSAR time series analysis is widely used for detection and monitoring of slow surface deformation. Persistent scatterer interferometric synthetic aperture radar (PS-InSAR) is based on a large number of SAR images, but small baseline subset interferometric synthetic aperture radar (SBAS-InSAR) only needs a small number of images and performs better than PS-InSAR for obtaining nonlinear deformation information. In this paper, 21 COSMO-SkyMed radar images acquired between 2016 and 2017 are processed for land subsidence monitoring with the Small Baseline Subset (SBAS) approach in Yongshan County transmission corridors in China.
