Application of the Sonar Equation to Dolphins Echolocation

2007

Au, Whitlow W.

The target detection capability of the Atlantic bottlenose dolphin (Tursiops truncatus) in the open waters of Kaneohe Bay, Oahu, Hawaii will be discussed using the noise-limited form of the sonar equation. In Kaneohe Bay, Tursiops typically emit short duration transient-like broadband echolocation signals with peak frequencies between 110- 130 kHz in (Au, 1980). Therefore the generalized or transient form of the sonar equation based on energy flux density instead of intensity must be used (Urick, 1983).
