Abstract: Ground-based synthetic aperture radar (GB-SAR) is a ground-based active microwave remote sensing technology developed in recent ten years. GB-SAR system can be used for non-contact, high precision, large-scale and long-distance deformation monitoring, which is of great significance in the field of deformation monitoring. Firstly, this paper introduces the basic theory and research status of GB-SAR. The main GB-SAR systems are summarized and the key parameters of the existing systems are listed in detail. Then we analyze the advantages and disadvantages of GB-SAR technology in the field of deformation monitoring such as infrastructure, landslides, mines, glacier movements and cultural relics protection and summarize the challenges faced by ground-based radar systems in practical applications. Finally, the application prospects are prospected from the aspects of deformation monitoring multi-dimension deformation and atmospheric correction.
