Analysis and Modeling of Echolocation Signals Emitted by Mediterranean Bottlenose Dolphins
EURASIP Journal on Advances in Signal Processing volume 2006, Article number: 025257 (2006)
We analyzed the echolocation sounds emitted by Mediterranean bottlenose dolphins. We extracted the click trains by visual inspection of the data files recorded along the coast of the Tuscany with the collaboration of the CETUS Research Center. We modeled the extracted sonar clicks as Gaussian or exponential multicomponent signals, we estimated the characteristic parameters and compared the data with the reconstructed signals based on the estimates. Results about the estimation and the data fitting are largely shown in the paper.
