Abstract:
An underwater acoustic transducer array comprising:a shaped acoustically absorptive backing material; a plurality of formed substrate sections positioned on said backing material and formed from a piezoelectric polymer, each section having a first surface and a second surface; at least one first conductive electrode positioned on said first surface of each section; and at least one second conductive electrode positioned on said second surface of each section, said first conductive electrode, said second conductive electrode, and said formed substrate section between said first and second conductive electrodes forming one transducer element of the array; said shaped acoustically absorptive backing material is a cylinder having flat, longitudinal surface cutouts formed thereon; and said plurality of formed substrate sections being formed as longitudinal surface sections wherein said first surface combines with an outer surface of said shaped acoustically absorptive backing material to form a cylinder, and said second surface being positioned on said longitudinal surface cutouts of said backing material.
