An exemplary embodiment of the present invention may include a cavitating body
sonar system and method. The method may include, in an exemplary embodiment: applying a receiving-while-transmitting
sonar signal processing to at least one cavitating body, over an entire range of achievable
sonar operating frequencies; applying transmit wave-form shaping to a RWT
sonar system employed on the cavitating body; applying
heterodyne filter frequency rejection to the RWT
sonar system employed on the cavitating body; applying detection
processing techniques to the RWT
sonar system employed on the cavitating body; employing at least one
transducer as an acoustical
transmitter near a scattering body comprising the cavitating body, wherein the at least one
transducer is strategically located with respect to said cavitating body, at least one target, and a
receiver, wherein the
receiver lies in a
shadow zone of the body, but the at least one target does not; and, employing at least one
transducer as an acoustical
transmitter near a scattering body comprising the cavitating body, wherein the at least one transducer is strategically located with respect to a cavity, at least one target, and a
receiver, wherein direct propagation of a transmitted
signal along the outside of the cavity to the receiver is inhibited, and reflected propagation from the acoustical
transmitter to the target and thence reflected to the receiver is not inhibited.
