Диаграмма направленности фазированной кольцевой акустической решетки

Abstract

The numerical analysis of the directive pattern of sound power radiation intencity of arrays consist of spherical sound radiators have been researched on a small distances with effects of sound. Аn influence of radiator numbers and distance between radiators have been researched on the possibility to provide a even concentration of radiation power in near arrays. Amplitude characteristics of field in far zone of annular phased antenna arrays are studied by program for computer analysis. Physical law of sound field spatial distribution of sound radiators has been careed out.
