Models for Computing the Directional Radiation of Sound from Sources on a Rigid Cylindrical Baffle

Abstract

The closed-form equations describing the acoustic radiation pattern for a source flush-mounted on a rigid cylindrical baffle are derived for three sonar transducer design configurations: two rectangular designs (Segment and Patch) and one circular. The derivation includes both application and an extension of developments by previous theorists. A computer program based on the derived closed-form equations is included to permit design investigation of the three (3) configurations. Preliminary results of the program agree with previously obtained patterns by other investigators for the same source. The program, however, allows extension to new configurations.
