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