Paper Abstract

The paper contains results of experimental investigations of the pressure field distribution in the vicinity of underwater sources of non-continuous radiating surface. Two sources were examined, each in form of 16-element array. The arrays are composed of circular piezoceramic pistons of the same dimensions and radiating properties. The elements of the first source are pistons of 25-mm-diam and resonant frequency equal to 600 kHz. The second of examined sources is using piezoelements of 10-mm-diam and resonant frequency of 1.5 MHz. Shown and characterized is the impact of the discontinuity of radiating surface on the nonlinear distortion process in the vicinity of the multi-element source.
