Detection, classification and localization of seabed objects with a virtual time reversal mirror
(Massachusetts Institute of Technology, 2009)
The work presented in this thesis addresses the problem of the detection, classification and localization of seabed objects in shallow water environments using a time reversal approach in a bistatic configuration. The ...
Modeling and frequency tracking of marine mammal whistle calls
(Massachusetts Institute of Technology, 2009)
Marine mammal whistle calls present an attractive medium for covert underwater communications. High quality models of the whistle calls are needed in order to synthesize natural-sounding whistles with embedded information. ...
Environmental analysis and prediction of transmission loss in the region of the New England Shelfbreak
(Massachusetts Institute of Technology, 2009)
A confluence of several coastal oceanographic features creates an acoustically interesting region with high variability along the New England Shelfbreak. Determining the effect of the variability on acoustic propagation ...
Forward sound propagation around seamounts : application of acoustic models to the Kermit-Roosevelt and Elivs seamounts
(Massachusetts Institute of Technology, 2009)
The Basin Acoustic Seamount Scattering Experiment (BASSEX) of 2004 was conducted to measure forward-scattering around the Kermit-Roosevelt Seamount Complex in the Northeast Pacific. The BASSEX experiment was focused on the ...
CFD study of hydrodynamic signal perception by fish using the lateral line system
(Massachusetts Institute of Technology, 2009)
The lateral line system on fish has been found to aid in schooling behavior, courtship communication, active and passive hydrodynamic imaging, and prey detection. The most widely used artificial prey stimulus has been the ...
