Multitone Matched-Field Processing in SWellEX-1.

Abstract

SWellEX-1 was a study of shallow-water propagation conducted near San Diego, CA, in August 1993. Data were recorded on an 88-meter aperture vertical line array while a source that emitted tonals from 70 Hz to 755 Hz was towed along range-independent and range-dependent tracks around the array site. One of the objectives was to study the effectiveness of matched-field processing as a means of source localization in a shallow-water environment. It was found that while narrowband matched-field processing tended to give ambiguous source localizations due to mismatch between the modeled and true propagation, it was possible to accurately track the source by simultaneously processing the transmitted tones.
