Abstract :
By exploiting the approximate linear relation of the absolute Doppler centroid against the slant range, a novel approach is proposed for resolving synthetic aperture radar (SAR) pulse repetition frequency (PRF)-ambiguity with high computational efficiency. Accuracy analysis and the experimental results with real data both demonstrate the effectiveness of the proposed method.
