Abstract:

The performance of directive receiving arrays is analyzed for spherically symmetric arrays, transparent to sound. Results are developed for two cases, where sensitivity is limited either to a then shell or to a complete spherical volume. In both cases, the magnitude of the sensitivity is uniform, but there is phase com pensation appropriate to a plane wave travelling in a single direction. Effects of finite spac ing between transducers in a point array are discussed qualitatively and briefly. Author
