Abstract :
An improved sub-aperture compensation algorithm for range-dependent motion errors in Synthetic Aperture Radar (SAR) with wide beam and wide swath is presented. The negative effect of strong Range Cell Migration (RCM) is removed and the range-dependent motion errors are corrected according to the relation between the Doppler frequency of a target and its location relative to the radar both in azimuth and range direction.
