Abstract
This project is the development of a single crystal underwater acoustic modem transducer for Unmanned Underwater Vehicles (UUV) which is compact in size, operates at low to moderately low center frequencies, in a broad band frequency range to accommodate state-of-the-art binary, FSK and spread spectrum signaling schemes that promote covertness. The device exploits the high coupling coefficient and low sound speed of single crystal piezoelectric materials and provides operation with high efficiency, broad bandwidth having high power factor, and is in a compact form-factor that minimizes the impact of unwanted hydrodynamic drag.
