Abstract : The patent describes a circularly housed transducer transmitting and/or receiving array of square transducer elements shaded to produce patterns equivalent to a transducer composed of a superpositioned set of concentric disk elements of consecutively smaller radii from the largest disk to produce stepwise shading thereby truncating a square array to maximize the radiating area and minimize the beamwidth with low side lobes.
