Abstract

The localization of underwater acoustic sources in a shallow water environment is addressed. Two array signal processing methods suitable for low-frequency signals in shallow water have been applied to data from an experiment conducted in the Barents Sea in 1999. The first method (matched-field processing) incorporates a full-field model of the acoustic signal in the signal processor. This method has been applied to vertical array data and to endfire horizontal array data. The second method (β-method) utilizes waveguide characteristics of the acoustic signal as measured on an endfire array and knowledge of the bathymetry of the propagation channel. A localization technique using data from a single hydrophone is also presented.
