Abstract:Underwater source localization from a passive array of acoustic sensors is a challenging problem, especially in complex environments characterized by multipath and reverberation effects, irregular seabed geometry, and low signal-to-noise ratio. This paper proposes a recursive Bayesian approach that propagates a spectral-element approximation of the wave equation to model the discretized space-time dynamics of the acoustic field conditioned on the position of the source, and sequentially estimates the field and… Show more
