Synthetic Aperture Radar (SAR) is an active microwave remote-sensing sensor that emits electromagnetic waves and records the signals reflected back from the earth, forming radar images. Microwave signals are transmitted and received independent of sunlight and can penetrate through clouds, SAR imaging is thus not affected by illumination or meteorological conditions. The amplitude and phase information in SAR images can be processed to accurately measure the deformation of the earth’s surface in a range from a few millimeters to tens of meters, playing an indispensable role in basic research and application fields such as geophysics, environment monitoring and nature hazard. Our research involves digital signal processing, elasticity/fluid mechanics, physical model inversion, big data and artificial intelligence and etc.
