Abstract :
A new squint dependent formulation of the known reflectivity displacement method (RDM) for motion error extraction is presented. This new formulation extends RDM applicability under high squint angles with a negligible computational overload. The data obtained is suitable for high quality synthetic aperture radar (SAR) processing with motion compensation avoiding the use of expensive inertial navigation system (INS) and GPS systems for many applications.
