Radar — Inverse Synthetic Aperture Radar
Information on Inverse Synthetic Aperture Radar
Synthetic aperture radar (SAR) techniques rely on motion of the radar system relative to the target. For SAR, the motion is assumed to be produced by a moving radar system against a stationary target. A stationary radar system can also make use of SAR techniques provided the target is moving in relation to the radar. This variation is known as inverse synthetic aperture radar (ISAR). Inverse synthetic aperture radar is popularly employed against ships bobbing in three dimensions on the ocean’s surface or against aircraft as they fly across the sky.
