Analysis and modeling of acoustic signals emitted by Mediterranean bottlenose dolphins

This work deals with the problem of modeling and estimating the parameters of sonar clicks and whistles emitted by the Mediterranean bottlenose dolphin (Tursiops truncatus). Click and whistle signals have been extracted from the real data recorded by the CETUS Research Center (http://cetus.supereva.it) along the Tuscany coast and have been modeled as multicomponent signals. The characteristic parameters have been estimated by a relaxation method and the results are presented.
