Submarine Launched Acoustic Communication Buoy using Single Crystal Sonar

For this Phase II SBIR program, TRS Technologies and Ultra Electronics Ocean Systems (UEOS) will team to design, build and test a buoy system for acoustic communications. Segmented single crystal rings for a 3" form factor will be made to provide a wide bandwidth for operation at two distinct frequency bands. TRS and UEOS will also team with the Woods Hole Oceanographic Institute to integrate their acoustic modem into the buoy and test the performance, including data transmission. The transmission electronics and packaging will be designed or modified, and the single crystal transducer will be tested for receive performance in water as well. Both the longitudinal and transverse piezoelectric modes will be explored for optimum performance in the smallest package possible. The Phase II option will integrate other buoy components towards achieving a whole system, as well as building a series of transducers for pressure and temperature testing.
