ABSTRACT:
A phased array radar system is disclosed, capable of simultaneously transmitting beams in different directions as well as simultaneous multiple beam beamforming with both linear and planar arrays. The system employs charge transfer device complex matrix multipliers to generate the phase weights necessary to produce and steer one or more transmit beams, and applies these phase weights to control directly the phasing of distributed transmitters individual to the antenna elements of the array. Similar matrix multipliers are employed to generate the phase weights necessary for beamforming on receive.
