Abstract
The project objective is to establish the technical feasibility of developing a miniaturized broadband HFTDA transducer for generation of four narrow inclined (Janus configuration) acoustic beams from a single small and flat aperture with performance comparable to large piston transducer assemblies used on current broadband acoustic Doppler velocity sensor commercial instruments. We will address three primary areas of concern: element-to-element crosstalk, array manufacturability, and miniaturization of beam- forming circuit. The Phase I effort will include theoretical predictions of the HFTDA beam patterns based on small scale testing results, an analysis of the robustness of the beam pattern to the random phase and amplitude errors in the individual transducers, and an experimentally verified HFTDA manufacturing approach.
