Signal Processing Applied to the Dolphin-Based Sonar System
The bottlenose dolphin has evolved a unique system of biosonar, or echolocation, that allows it to exploit a visually limited littoral niche. The effectiveness of dolphin echolocation at finding and identifying submerged objects is unsurpassed by man-made hardware systems built for similar tasks. It has become a model system from which to draw hardware and signal processing design concepts and ...
متن کاملThree-dimensional Computer Modeling of Biosonar Emission in the Common Dolphin
Severat delphinid species are known to possess a highly sophisticated and adaptable biosonar system, yet the exact acoustic mechanisms involved in signaf generation, emission, and reception remain poorly understood. Recently, a novel computatiomd approach was used to investigate the acoustical mechanisms of dolphin biosonar. Three-dimensional acoustic simulation techniques and a new method for ...
متن کاملHearing Sensation Levels of Emitted Biosonar Clicks in an Echolocating Atlantic Bottlenose Dolphin
Emitted biosonar clicks and auditory evoked potential (AEP) responses triggered by the clicks were synchronously recorded during echolocation in an Atlantic bottlenose dolphin (Tursiops truncatus) trained to wear suction-cup EEG electrodes and to detect targets by echolocation. Three targets with target strengths of -34, -28, and -22 dB were used at distances of 2 to 6.5 m for each target. The ...
متن کاملDolphin hearing during echolocation: evoked potential responses in an Atlantic bottlenose dolphin (Tursiops truncatus).
Auditory evoked potential (AEP) responses were recorded during echolocation in an Atlantic bottlenose dolphin (Tursiops truncatus) trained to accept suction-cup EEG electrodes and detect targets by echolocation. AEP recording was triggered by the echolocation clicks of the animal. Three targets with target strengths of -34, -28 and -22 dB were used at a target distance of 2 to 6.5 m for each ta...
متن کاملA Review of New Understanding of the Role of Individual Structure within the Head of Dolphins in Formation of Biosonar Signal and Beam
In recent years a number of experiments and measurements associated mainly with the Atlantic bottlenose dolphin (Tursiops truncatus) and one with the harbor porpoise (Phocoena phocoena) have shed some interesting light on biosonar signal production and propagation in the head of the animals and the formation of the biosonar beam. In this short review, the results of these experiments will be ta...
