Abstract

The specific features of the influence of such factors as the damping of a longitudinal wave in a medium, its transformation into a transverse wave during transmission, and the radiation directivity of array elements on the characteristics of a signal of a normal linear phased-array transducer are considered. Very simple methods for taking these factors into account are presented. It is noted that increasing the dimensions of array elements may lead to a significant reduction of the amplitude of the total transmitted signal in the transducer near-field zone.
