Abstract : A beamforming system for a linear phased array antenna system which can be used in a monopulse transceiver, comprises a pair of series-connected parallel-plate-constrained unfocused lenses which provide a suitable amplitude taper for the linear array to yield a low sidelobe radiation pattern. Digital phase shifters are used for beam steering purposes and the unfocused lenses decorrelate the quantization errors caused by the use of such phase shifters.
