Beamforming array antenna control system and method for beamforming using the same

摘要

A control system connected to a plurality of array antenna performs beamforming. In order to perform the beamforming, the control system receives response beams inputting to a first antenna group predetermined from a plurality of array antenna in response to radiate beams and decides a sector having comparatively stronger intensity. And the control system receives response beams inputting to a second antenna group, decides a plurality of beam levels and decides a final beam pair among the plurality of the decided beam levels.

1. A method for beamforming at a control system connected to a plurality of array antennas, the method comprising:
requesting a first antenna group to radiate beams to a plurality of predetermined sectors, wherein the first antenna group is predetermined from the plurality of array antennas; receiving response beams inputted to the first antenna group in response to the radiated beams; selecting, from the plurality of predetermined sectors, a sector related to a response beam having a comparatively stronger intensity among the received response beams inputted to the first antenna group; setting up a second antenna group including the first antenna group and a plurality of antennas adjacent to the first antenna group as a second antenna group; requesting the second antenna group to radiate beams to a plurality of sub sectors in the selected sector; receiving response beams inputted to the second antenna group in response to the radiated beams of the second antenna group; selecting, from the plurality of sub sectors, a sub sector related to a response beam having a comparatively stronger intensity among the received response beams inputted to the second antenna group; deciding a plurality of beam levels through by beam level training with the selected sub sector; and deciding a final beam signal pair from the plurality of beam levels by high resolution (HRS) beam training with the selected sub sector.
