Query: Acoustic Source Localization in Shallow Water: A Probabilistic
  Focalization Approach   This paper presents a Bayesian estimation method for the passive localization
of an acoustic source in shallow water. Our probabilistic focalization approach
estimates the time-varying source location by associating direction of arrival
(DOA) observations to DOAs predicted based on a statistical model. Embedded ray
tracing makes it possible to incorporate environmental parameters and
characterize the nonlinear acoustic waveguide. We demonstrate performance
advantages of our approach compared to matched field processing using data
collected during the SWellEx-96 experiment.
