Abstract:
The design, development, and analysis of a unique type of underwater acoustic are discussed. The transducer is in the form of a linear array of discrete elements and is required to have a constant transmitting voltage response and carefully controlled directivity characteristics over a two-octave bandwidth. A generalized model of linear array of cylindrical piezoelectric ceramic acoustic radiators is developed and applied to the design of a prototype which operates over approximately half of the required bandwidth. The prototype transducer was built, and the measured results are compared with those predicted by the model. Recommendations are made for improving the performance of both the prototype and the array required to meet the full specified bandwidth. (Author)
