DOI: 10.1109/lgrs.2022.3180751
Abstract: Beamforming is extensively used in underwater acoustic imaging systems. As a high-resolution variety, a Bayesian compressive beamformer treats the acoustic echo of each snapshot independently and achieves enhanced recovery performance. However, its associated computational cost… read more here.
