发明名称 Piecewise coherent beamforming for satellite communications
摘要 The satellite communication system uses defocused feed arrays to generate a large number of beams that cover a number of regions. The ground gateways are assigned the same frequency spectrum. The beams are divided into multiple groups and each group is controlled by a different ground gateway. The signals within each group are coherent. Each gateway can then control the set of beams landing on its neighboring territory.
