Abstract
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 recei…
