Imaging radar are radar systems used in remote sensing usually produce images of some kind. The most common remote sensing imaging radar systems are the side-looking airborne radars (SLARs) that produce continuous strip images. The antenna points to the side with a beam that is wide vertically and narrow horizontally. The image is produced by motion of the aircraft past the area being covered. SLAR imagery has been used in geomorphology, geology, land use, forestry, natural vegetation, physical oceanography and other fields. Synthetic Aperture Radar (SAR) provides the capability of acquiring imagery inclement weather or during night as well as day.
