Adaptive antenna array pattern synthesis using recursive minimum-norm solution with constraint selection and phase optimization

An algorithm has been developed to provide the uplink received antenna with beamforming capability for selective earth coverage and jamming protection for military satellite communications applications. The problem can be formulated as to determine the control weight to meet the user gain and jammer null requirements in their known directions subject to the norm constraint. A recursive procedure has been developed which provides flexibility in the determination of the constraint vector, the constraint order and the constraint phase optimization. The recursion can also be implemented as updating of the null space
