DIRECTIVITY FUNCTION OF A GENERAL RECEIVING ARRAY FOR SPHERICAL AND PLANE SOUND WAVES.

Abstract

This report, which resulted from work done in the field of long-range sonar, makes available general expressions for the determination of directivity functions of arrays of any size and shape, and with any distribution of elements. The directivity functions of more conventional array forms, such as linear and circular arrays, are shown to be special cases of the general case. General expressions are derived for directivity functions when the source is at a finite distance and the wave front is therefore curved. (Author)
