VIRTUAL BEAM FORMING IN ULTRA WIDEBAND SYSTEMS

Systems and methods include up-converting a UWB frequency pulse from a UWB radar unit to a V band frequency pulse; transmitting the V band frequency pulse via an active array antenna; receiving a V band echo pulse via the active array antenna; down-converting the V band echo pulse from the active array antenna to a UWB pulse; and feeding the UWB pulse to the UWB radar unit for processing by the UWB radar unit. A V band antenna system includes: an antenna board that defines an antenna plane being the plane of the board and comprising a plurality of antenna elements; a mother board providing a corporate combining feed to the antenna board; and a power management board to which the antenna board and mother board are mounted perpendicularly to the antenna plane, wherein the antenna elements provide a beam forming antenna for ultra wide band pulses at V band frequencies.
