OPTIMIZATION OF THE BACK-TO-FRONT SUPPRESSION AND FREQUENCY BANDWIDTH RELATIONSHIP FOR THREE-DIMENSIONAL ACOUSTIC ARRAYS.

Abstract

For those three-dimensional arrays whose radiationpattern function is the product of an end-fire-arraypattern function and a broadside-array-pattern function, a procedure has been developed for optimizing the frequency range vs the back-to-front-suppression relationship. That is, the amplitude coefficient distribution for the array is determined by a Tchebyscheff polynomial technique so that (a) the back-to-front suppression is maximum over a predetermined frequency range or (b) a specified back-to-front suppression is available over a maximum frequency range.
