Abstract
We propose a compact broadband underwater cylindrical transducer with directional capabilities for acoustic communications (ACOMMS) for unmanned underwater vehicles (UUVs) and gliders. Our proposed solution is to incorporate single crystals and directional capabilities into the acoustic modem transducer, thereby increasing overall system capability. BTech has designed and built improved modem transducers using segmented single crystal (PMN-PT) rings, which offer increased bandwidth and electroacoustic efficiency. BTech has also demonstrated directional capabilities with PZT based modems. The two technologies will be combined to achieve a directional broadband single crystal modem.
