ADAPTATION OF DOLPHINS (TURSIOPS TRUNCATUS) LOCATION SIGNALS WHEN SEARCHING AND RECOGNIZING OBJECTS HIDDEN BY SEA SEDIMENTS
An experimental study was conducted to research dolphins sonar adaptation capabilities for location of objects obscured by marine sediments. It was shown that dolphins are able to alter spectral and temporal characteristics of their location signals. Adaptive change of length, spectral width, and amplitude of impulses provides optimal tools to fight interference and allows dolphins to effectively identify objects. SUMMARYThis work describes dolphins search, location and recognition objects hidden by sea sediments and changes in its location signal structure.
