摘要： Method and system are provided for reducing the AWV table size for phased-array antenna. In one novel aspect, the AWV table is decomposed to a combination of a first AWV table and a second AWV table, with a combined size smaller than the size of the AWV table. In one novel aspect, a group of decomposable AWVs are identified and each decomposed into a decomposed first AWVs and a decomposed second AWVs. In one embodiment, the decomposable weights W that are decomposed into Wh being a function of both elevation θ and azimuth (φ and Wv being a function of elevation θ only. In one novel aspect, the AWV table for a phased-array antenna with N antenna elements with Mv weights in a vertical direction and Mh weights in a horizontal direction is decomposed into a first AWV table and a second AWV table with a combined size of N*(Mv+Mh).
