Through-Ice Acoustic Source Tracking Using Vision Transformers with Ordinal Classification
Ice environments pose challenges for conventional underwater acoustic localization techniques due to their multipath and non-linear nature. In this paper, we compare different deep learning networks, such as Transformers, Convolutional Neural Networks ...

Fast Bayesian acoustic localization [PDF]
We derive a probabilistic formulation, based upon Bayes' rule, for the acoustic localization problem. The resulting formula is shown to be closely related to the energy of a conventionally beamformed signal. We then present a close approximation to both which is much faster to compute — by two orders of magnitude with our experimental setup.

Source Localization in Random Acoustic Waveguides [PDF]
Mode coupling due to scattering by weak random inhomogeneities in waveguides leads to loss of coherence of wave fields at long distances of propagation. This in turn leads to serious deterioration of coherent source localization methods, such as matched field.
