Efficient Motion Compensation of a Moving Object on SAR Imagery Based on Velocity Correlation Function

Current motion compensation algorithms for a moving object on synthetic aperture radar (SAR) imagery by refocusing are accurate, but they suffer from a severe computational efficiency problem. If the step size of an assumed target velocity is too large, one could miss the true target velocity, where...
