After range cell migration correction in the range-Doppler domain, it is found that the two-dimensional envelope of a synthetic aperture radar (SAR) moving target exhibits a skew with the slope proportional to its Doppler ambiguity integer. Therefore, a novel approach is proposed for Doppler ambiguity resolving of SAR moving targets based on linear residual migration correction. The results of both Monte-Carlo trials and real data are provided to demonstrate the effectiveness of the proposed method.
