- W4386202820 abstract "Dealing with range ambiguity is a hot issue in SAR signal processing. One limitation of current algorithms is their poor robustness to noise and the energy of ambiguous targets, which can lead to performance degradation in complex environments. This letter proposes a new algorithm for range ambiguity suppression in SAR. The algorithm utilizes the orthogonality of the transmitted signal to separate the echo signals of the main region and the ambiguous area, and subsequently applies the alternating direction method of multipliers (ADMM) algorithm to perform joint sparse recovery on both areas. Experimental results show that the proposed method can effectively suppress range ambiguity, and it has a good ability to maintain the weak targets and the details of the main region’s image." @default.
