- An algorithm has been developed to control the antenna array beam pattern for satellite communication applications where theuplink received antenna is desired to provide beamforming capability for selective earth coverage and jamming protection. The problem canbe formulated to determine the antenna weight to meet the user gain and jammer null requirements in their known directions, subject to thenorm bound constraint of the weight. The algorithm makes use of the orthogonal decomposition of the weight vector and a recursive procedurethat provides flexibility in the determination of the constraint vectors, the constraint order, and the constraint phase optimization.[ 11 J.
