Synthetic aperture radar (SAR) is an active remote sensing tool operating in the microwave range of the electromagnetic spectrum. It uses the motion of the radar transmitter to synthesize an antenna aperture much larger than the actual antenna aperture in order to yield high spatial resolution radar images (Curlander & McDonough, 1991). It has been applied to military survey, terrain mapping, and other fields for its characteristics of working in all weather during day and night.
