High-resolution DOA estimation achieved by a single acoustic vector sensor under anisotropic noise

Open Access Research Article 2023

Applied Acoustics

An AVS measurement system is designed, and an Anisotropic Sparse Bayesian Learning (SBL) method (the A-SBL method) is proposed to model and estimate the anisotropic noise of the AVS system for use in (among other things) underwater noise detection.
