Abstract:

A frequency independent acoustic antenna has an acoustic filter plate located between a lens and sensor-transmitter. When used as a receiver this arrangement of components enables the lens to receive plane waves emanating from a source. This results in materially enhanced beam forming characteristics and performance. The arrangement is also suitable for use in the transmitting mode. Patents
