A Scanning Sonar Transmitter Employing the Matrix Phase Compensator and Silicon Controlled Rectifier Switches.

Abstract : A matrix phase compensator for the AN/SQS-4 Mod 3 sonar, capable of forming any of 48 beams at the 50 kilowatt level, was constructed and tested. High-speed semiconductor switching circuitry was developed for stepping the formed beams at wide variations in rate. Incorporation of the equipment into the AN/SQS-4 should provide improved performance and reduced cost and complexity as compared to current scanning sonars. (Author)
