Probabilistic estimation of merchant ship source levels in an uncertain shallow-water environment
Tollefsen, Dag; Hodgkiss, William S.; Dosso, Stan E.; Bonnel, Julien; Knobles, David P. (2021-11-13)The estimation of ship source levels (SSLs) in shallow-water environments can be complicated by sound interaction with the seabed. Uncertainty in seabed properties influences SSL estimates, and it is of interest to mitigate ... -
Ship source level estimation and uncertainty quantification in shallow water via Bayesian marginalization
Tollefsen, Dag; Dosso, Stan E. (2020-04-17)This paper applies a non-linear Bayesian marginalization approach to ship spectral source level estimation in shallow water with unknown seabed properties and uncertain source depth. The algorithm integrates the posterior ... -
Ship-of-opportunity noise inversions for geoacoustic profiles of a layered mud-sand seabed
Tollefsen, Dag; Dosso, Stan E.; Knobles, David P. (2019-04-30)This paper considers the use of broadband noise from a ship-of-opportunity in statistical inference for estimating geoacoustic parameters of a layered mud-sand seabed model via trans-dimensional (trans-D) Bayesian matched-field ... -
Source Localization With Multiple Hydrophone Arrays via Matched-Field Processing
Tollefsen, Dag; Dosso, Stan E. (2016)This paper considers approaches to combining information from multiple arrays in matched-field processing (MFP) for underwater acoustic source localization. The standard approach is to apply conventional MFP for each array ... -
Three-dimensional multiple-source focalization in an uncertain ocean environment
Tollefsen, Dag; Dosso, Stan E. (2013)This letter develops a Bayesian focalization approach for three-dimensional localization of an unknown number of sources in shallow water with uncertain environmental properties. The algorithm minimizes the Bayesian ...
