摘要: A beam forming apparatus of a satellite is configured to: define perimeter coverage area, and coordinate grid polar system so as to divide the area into plurality small areas; calculate coordinates borders between basic cells in Cartesian system, being shaped regular hexagons arranged be contact with one another along their sides at vertices or circles circumscribing hexagons; new by converting, through transformation, system; set amplitudes phases antenna devices that are suitable form beams respective directions cells.
