Abstract
Uniformity of constituent projector elements is a prerequisite for building a high-performance underwater transmit array. Unless the element-to-element variations in transmitting voltage response (TVR) and directivity fall within specified limits, the resulting acoustic performance of the array will suffer significantly in terms of its sound output and directivity. Here, we consider a case in which projector elements exhibit a large scatter in TVR, say, over 6 dB, and present a design guide to still get the most of the array. The focus of the study is to explore how the relative placement of projector elements affects their mutual interaction and ultimately leads to the overall characteristics of the array. Finite element computations are carried out to derive an optimized design and the design guide.
