Abstract: Differential synthetic aperture radar interferometry (DInSAR) can realize earth surface deformation observation with precision of cm order and large spatial coverage. It has become an important tool for measuring crust deformation, and has been playing an increasingly prominent role in measuring earthquake deformation. In this paper, we present a summary of the features of microwave surveying, explain basic radar image processing method and analyze the main factors influencing the precision of InSAR technique. In view of the most recent rsults, we analyzed several approaches of earthquake deformation studies using radar remote-sensing images, and discussed advances in interseismic, coseismic and post-seismic deformation observation and research. We also discussed main difficulties in applying DInSAR to earthquake deformation research in China.
