A bayesian framework for geoacoustic inversion of wind-driven ambient noise in shallow water
Jorge, E. Quijano; School of Earth and Ocean Sciences, University of Victoria, 3800 Finnerty Road, Victoria, BC V8P 5C2, Canada - Stan, E. Dosso; School of Earth and Ocean Sciences, University of Victoria, 3800 Finnerty Road, Victoria, BC V8P 5C2, Canada - Dettmer, Jan; School of Earth and Ocean Sciences, University of Victoria, 3800 Finnerty Road, Victoria, BC V8P 5C2, Canada

Enlaces:	Bayesian inversion is applied to estimate the joint posterior probability density (PPD) of geoacoustic parameters. The PPD is sampled by a reversible-jump Markov chain Monte Carlo (rjMCMC) algorithm, which uses an extended Metropolis-Hasting (MH) criterion that allows trans-D jumps between…

Sparse broadband acoustic response estimation via a gaussian mixture model with application to m-ary orthogonal signaling
Gendron, Paul J.; Maritime Surveillance Division, Code 56490 Space and Naval Warfare Systems Center Pacific, San Diego, CA, United States

Formato:	info:eu-repo/semantics/article, info:eu-repo/semantics/publishedVersion, ,
Enlaces:	Shallow water acoustic response functions at high frequencies and large bandwidths exhibit spatio- temporal variability that depends greatly on the propagation media's volume and boundary conditions as well as system source-receiver motion. For this reason practical acoustic systems invariably must…
