Abstract
A new technique is presented for range-migration correction in SAR imaging. In the range-Doppler domain, the samples at a Doppler frequency constitute a Doppler slice. Different Doppler slices have similar envelopes. Based on this similarity, the Doppler slices are shifted and aligned in range to correct range migration. The technique applies even if the prior knowledge about the relative motion between the radar and the target is unavailable.
