Title: Low Frequency Projector for Long Range Acoustic Communications

Agency: DOD

Contract: N00014-11-M-0254

Award Amount: $79,916.00

Abstract:
Etrema proposes to develop a free-flooded Galfenol split-ring transducer that will provide 50-75 Hz of bandwidth on a 200 Hz carrier wave capable of operating at depths up to 1000 m with a source level greater than 190 dB re 1uPa @ 1m. While there are no specifications on size, the desire expressed by the technical point of contact is for a source that will fit on a standard pallet. By combining the depth-independence and bandwidth of a free-flooded magnetostrictive ring with the compact size of a split-ring, the resulting transducer should meet the objectives for the communications application. Design options which decrease size and improve performance will be explored.
