FORMATION OF SONAR CHANNELS BY CHARGE - COUPLED DEVICES ABSTRACT OF THE DISCLOSURE Formation of channels for all-round passive sonar systems by the technique of charge-coupled devices. The shift register receives the multiplexed signals of the M transducers forming the listening base of the sonar system. The shift register has different series of sub-contacts, each serie corresponding, at one moment, to the signal of one of the transducers. The adding of the weighted signals of one serie gives an interpolated si- gnal of the corresponding transducer. The such obtained delayed signals are weighted and added, such obtaining the preformed channels.
