DEVELOPMENT OF A TOWED PHASED ARRAY DOPPLER SONAR SYSTEM
Abstract
As a first step in maintaining excellence in Doppler sonars for a variety of Navy applications, we propose to modernize and repackage an existing 220-kHz phased-array Doppler system to allow it to be towed behind a ship while relaying data to the ship via a fiber-optic link. The resulting system will be configurable in a variety of geometries, but the most immediate use will be projecting a wedge athwartship and downward. This operation will allow imaging of velocity with 1-2-m resolution in a ~300-m-wide ``quarter-tube??? of ocean as the ship steams along, giving a novel view of sharp upper-ocean flows such as fronts and filaments.
