Abstract
Spaceborne synthetic aperture radar (SAR) has been widely used in the national defense, geologic mapping, disaster estimation, and other fields. This technique has realized the technological leap forward from low-Earth-orbit (LEO) to medium-Earth-orbit (MEO)/geosynchronous-Earth-orbit (GEO) SAR imaging, single- to multichannel processing, the resolution level of the meter to submeter, and single to multiple imaging modes in recent years.
