dc.description.abstract | A design is outlined in which three different kinds of transducer elements are arranged concentrically and in near proximity. It will be possible to drive the elements simultaneously, thus forming three coaxial beams at distinct frequencies. Under good signal-to-noise conditions, the acoustically sampled volume will be similar for each of the beams. | en_US |
