recommendations! Published in 2024 at "Inverse Problems"

DOI: 10.1088/1361-6420/ad3b33

Abstract: The retrieval of non-Born scatterers is addressed within the contrast source inversion (CSI) framework by means of a novel multi-step inverse scattering method that jointly exploits prior information on the class of targets under investigation… read more here.

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.

DOI: 10.1109/tap.2017.2655013

Abstract: The problem of estimating the dynamic direction of arrival (DOA) of far-field signals impinging on a uniform linear array, with mutual coupling effects, is addressed. This paper proposes two novel approaches able to provide accurate… read more here.

DOI: 10.1109/tvt.2017.2669920

Abstract: In wireless localization services, a wideband spectrum is required for high resolution ranging. For this purpose, unlicensed bands have received substantial interest for their potential to reduce deployment cost. However, in the unlicensed spectrum, narrowband… read more here.
