ABSTRACT:
A sonar system using closely spaced or interleaved projector and receiving transducer elements with a power inductor connected in series with the projector array transmits three separate frequencies and utilizes a resonant circuit connected across the projector array, and a switch alternately connecting the array to the transmitter or the resonant circuit. The resonant circuit has two parallel branches with an inductor in one branch and an inductor, a capacitor and a resistor in the parallel branch. An alternate embodiment includes a variable capacitor in series with the parallel circuit to simplify the tuning for individual installations. Values of the components were chosen to provide impedances looking into the resonant circuit which tend to maximize the "stiffness" of the projector elements for all the received frequencies, thus inhibiting the tendency of the projector elements to receive and reradiate echo signals during the receiving cycle of the sonar system.
