ACOUSTIC INTERACTION FOR LINEAR AND PLANAR ARRAYS OF SMALL MAGNETOSTRICTIVE-STACK SONAR TRANSDUCERS AT AN AIR-WATER SURFACE.
Abstract
Experiments and theoretical developments for the acoustic interaction among small 20 kc/sec magnetostrictive-stack sonar transducers in linear arrays of two and three and planar arrays of three and four at an air-water surface are described. The interaction radiation resistance and reactance are studied as functions of number, spacing, relative position and relative phase of the transducers. Analysis and a graph are presented for source and sink regions for transducer operation as a function of spacing and relative amplitude. The theoretical development for this work is based on interacting dipoles in an infinite medium. It is hoped that the results of this study can be used in the design of more efficient sonar arrays.
