摘要： A control system connected to a plurality of array antenna performs beamforming. The control system requests a first antenna group predetermined from a plurality of array antenna to radiate beams to a plurality of predetermined sectors. The control system receives response beams inputting to the first antenna group in response to the radiated beams, decides a sector having comparatively stronger intensity among response beams for a plurality of sectors as an optimized sector, and requests a second antenna group to radiate beams to a plurality of sectors included in the optimized sector. The control system receives response beams inputting to the second antenna group, decides a sector related to a beam having comparatively stronger intensity among response beams for the plurality of sectors in the optimized sector, decides a plurality of beam levels, and decides a final beam pair among the plurality of the decided beam levels.
