A Tuned Auto-Compensator for Residual Antenna Motion in Synthetic Aperture Radar Systems

We present a process for the removal of the image corrupting effect of undetected antenna motions in synthetic-aperture radars. This is a signal processing scheme tuned to the characteristic frequencies of the residual antenna motion, and performs particularly well for vibrations. It has no stringent requirements on the existence of dominant point reflectors in the scene.
