Abstract: The microphones are spaced at specified distances, and a transmitter is mounted in a float from which runs a second cable to a device receiving signals from the microphones and applying them to the transmitter. A propellor (27) is attached to the end of the first cable (37) which moves it in a specified direction. A parachute (26) resisting this movement is attached to the other cable (37) end. An electronic unit (25) is connected through a secondary cable (24) to the transmitter float (22) which has an antenna (45) in the form of an upwards projecting spike.

Abstract: HYDROPHONE ARRAY SYSTEM A hydrophone array system comprising a plurality of hydrophones fastened to a cable is deployed beneath the sea in a substantially horizontal straight line. A small powered thruster fastened to one end of the cable urges it in a first direction and this urging is resisted by a member, such as a drogue or an anchored subsurface float, fastened to the other end of the cable. Individual signals from each of the hydrophones are conducted to the surface where they are processed and transmitted by a radio link to a nearby aircraft or surface vessel. Beam forming and analysis is performed aboard the aircraft or surface vessel.
