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

This SBIR Phase I Proposal addresses the need for Next Generation Targets. The present EMATT diameter is 4.875 inches and with its current conventional cylindrical transducer is limited in attaining desired levels at lower frequencies. The objective of the Phase I SBIR program is to define and develop concepts for a candidate wide band transducer system that provides the acoustic response over the low frequency and sonar band spectrum and a design that fits within a threshold maximum diameter of 12.75 inches by proposing a six inch diameter design and the possibility of a low frequency design which fits into a 4.875 inch diameter vehicle. We propose to bridge the low frequency acoustic performance gap between the current A-sized EMATT ASW target and the MK30 performance. The major challenge is to produce the acoustic performance in the low frequency range within a small diameter ASW target. Image Acoustics is proposing an advanced transducer that would provide wideband acoustic performance for the next generation small diameter expendable mobile training targets.
