<p>A cylindrical array of radiating elements or sonar transducers each of which is coupled by a clipping circuit to a multiply tapped shift register for imparting delays to the signals of the elements for forming a beam of radiant energy. Sidelobes on the radiation pattern are reduced by multiplying the signals of the shift registers by weighting factors prior to their summation for forming a beam, clipped signals serving as unitary factors of positive or negative sign in the multiplication.</p> |
