In the process, the persistent scatterer (PS) technology was utilized to obtain the deformation of the scene. Firstly, the full basic PS process chain for deformation generation is presented. Secondly, the ground-based SAR system and the data acquisition of geometry are described briefly. Furthermore, the theoretical developments are complemented with the process of real data which is acquired in the experiment. Finally, the comparison between experimental results and local measurements is discussed, which demonstrated the feasibility of our GBSAR system to obtain high-precision deformation. 收起
