Wideband Acoustic Signature Capability for Next Generation Mobile Anti-Submarine Warfare (ASW) Training Target

Our Phase II technical objectives include modeling, designing, fabricating and testing 4.875”and 12.75” vehicle sized Trioid transducers and extending the low frequency operation of the current EMATT Mark 39 training vehicle. In addition to this, we plan to approach the operating band of a MK 30 but with a diameter at approximately one-half the MK 30. This will be accomplished through FEA modeling and optimization of our Trioid Model D which was evaluated during the Phase I program and shown to be a favorable design choice for this program. During the Phase II basic program the FEA designs would be finalized. In addition we would consider and evaluate means for achieving a greater source level and/or operating at a greater depth, if desired. After conversations with the TPOC and associated engineers, we would design, fabricate and test full-sized models alone and mounted in vehicles. Results of this development will be documented in progress and final reports.
