Abstract
Defence Research Establishment Atlantic has developed a wide-band sonar (WBS) for collecting acoustic data in the open ocean. The system employs a parametric array transmitter which enables direct measurement of seabed parameters in shallow water. To complement the parametric transmitter, a pair of 6-channel receivers have been developed for the system; a 6-channel superdirective line array is used as the principle receiver and a tri-axial intensity array is used to localize the platform and measure ambient noise directionality. In this paper the attributes of the WBS will be outlined, the typical experimental geometries will be described, and a sample of the measurements made with the system during the Boundary 2001 trial will be presented.
