Abstract
A sonar system utilizing a common LC tuned circuit for both the transmitter portion and the receiver portion of the electronic system so that both receiver and transmitter are tuned to the same frequency. The transducer is isolated from the LC tuned circuit so that the impedance characteristics of the transducer will not operate to change the main frequency of the tuned circuit. Thus interchangeable transducers may be utilized with the receiver-transmitter circuitry. The transmitter power pulses are generated by a novel Class C pulse circuit providing short time width, high intensity power pulses to the transducer.
