A sonar system includes a forward looking array which is embedded in a
cavitator for generating a gaseous cavity which minimizes hydrodynamic
noise resulting from turbulent pressure fluctuations. A marine vessel
incorporating the sonar system includes a hull, a hydrofoil suspended
beneath the hull by a strut, and a cavitator for generating a laminar
flow over the hydrofoil and for creating a cavity for eliminating
turbulent flow contact. The cavitator is located at a leading edge area
of the hydrofoil. The sonar array is embedded into the cavitator.
