Method for Designing an Acoustic Array

Abstract

A method for designing an acoustic array includes establishing a desired beam pattern, acoustic wavelength and beamwidth for the array. Geometric parameters are calculated from these constraints. The array is modeled as a plurality of elements positioned in accordance with the geometric parameters. An amplitude shading function is calculated. An array of acoustic elements is constructed having an area calculated from the calculated amplitude shading function. An acoustic array designed by this process is further provided.
