This paper presents recent findings on the biosonar echolocation waveforms of Bottlenose dolphins (Tursiops truncatus). The complex spectral shape of the waveforms (bimodal spectrum) and the dynamics of the click trains are discussed. It is shown that these waveforms have not only the smallest possible time-bandwidth product, but that they are in fact minimum phase waveforms (i.e., the phase is a function of the autospectrum). The characteristics of the waveforms including time/frequency distribution, autocorrelation, and the bimodal spectral structure of these waveforms are discussed. An interpretation of these features is proposed with respect to echolocation tasks in shallow water. It is shown how these waveforms may be used for optimizing both near range resolution and sidelobe levels in the processed echo waveforms. Examples are shown on how GORCA Technologies, Inc. (GTI) exploits such features in the development of a biomimetic SONAR. Finally, this paper presents examples of GTIs proprietary broadband adaptive algorithm performance, using animal echolocation data. In the data used for this study, the animal performed a three-alternative match-to-sample task (data courtesy of the biosonar program at SPAWAR San Diego). [Work sponsored by ONR.]
