Abstract:
An apparatus includes a plurality of feeds that form analog beams. The plurality of feeds is divided into a plurality of panels, each panel including one or more feeds from the plurality of feeds. The apparatus also includes processing circuitry, which determines a target area for communications coverage and divides the target area into a plurality of regions. The processing circuitry generates, for each region, a plurality of analog beams. A subset of panels of the plurality of panels generates one or more analog beams of the plurality of analog beams. The plurality of analog beams covering each region forms a cluster. The processing circuitry generates, in each cluster, one or more hybrid beams. Each hybrid beam is a digital beam that is generated by combining one or more analog beams of the plurality of analog beams corresponding to the cluster.
