ABSTRACT:
A parallel digital beam-former for an array of hydrophones. The output of ch hydrophone is fed into a different shift register. Each register stores the sampled time history of the hydrophone. The contents of each register are fed serially into a different gating circuit in the time interval between each new input signal sample and the output of each gating circuit is fed in parallel with the output of each of the other gating circuits to a group of beam gates. The output of each beam gate is then fed to a different binary counter which sums the signals. Each binary counter is associated with a different beam.
