[Shape acoustical recognition and characteristics of sonar signals by the dolphin T. truncatus].
During the shape acoustical recognition process, the signal processing reveals two phases in the T. truncatus sonar emission. In the course of the first phase, the wide-band signals are invariant, during the second phase, near the end of the approach, their temporal and spectral characteristics change along with the shape of the objects to identify.
