Abstract:

The use of amplitude and phase shading on a pair of concentric piston radiators has been employed as a means for controlling the acoustic radiation patterns for a small flush face transducer which is intended for use as a 75 kHz sound source in the underwater tracking of vehicles. A description is given of the design, construction and tests of several models of the composite piezoelectric ceramic transducer. Results indicate that this appears to be a feasible method for achieving a principal design goal of a broad beamwidth radiation pattern with a pronounced reduction in source level along the transducer axis. Some additional development is needed for achieving a configuration which might be optimum for production. Author
