This paper describes a method for detection of marine bioacoustic signals. The method is based on higher-order statistics technique to identify transients in passive array data. A prototype underwater unit with integrated phased circular array has been engineered to test the approach. Results of in-situ measurements obtained using artificial targets are presented. Specifically, implementation of Jarque-Bera test is shown to have resulted in a substantial increase in detection efficiency as against that achieved by traditional signal processing techniques.
