Abstract : A combination of integrated circuit (IC) flatpacs used in combination to switch selected sonar microphone inputs from a circular receiving array to position a beam containing a sounding target intermediate to an equal number of left and right microphone pickups and selectively switching through weighted delay circuits for beam forming to present the target in this receiving beam electronically on a flat display with digital control of coarse seven and one-half degrees and fine one-tenth degree increments to provide a display of the bearing of the target.
