Gaseous Cavity for Forward-Looking Sonar Quieting

Abstract

This patent application discloses a sonar quieting system for a forward-looking sonar array. The sonar quieting system includes a cavitator for forming an envelope; a strut for supporting the cavitator to a marine platform, such as a ship; a forward-looking sonar array mounted to a forward face of the cavitator; and a ventilation system for pumping a gas, such as air, into the envelope to create a gas cavity that envelops the supporting strut and equipment downstream of and during a forward movement of the cavitator.
