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 ...
