To achieve adaptive multibeamforming to allow reconfiguration in SSW-TDMA satellite communications, a system for narrow band adaptive multibeamforming is described in this work. The signal processor allows an unconstrained array to form independent beams for the impinging directions without any prior knowledge of them. The simultaneous use of constant modulus and minimum variance (least-mean square loops) is done by an especial policy of master-slave for subarrays or local beams which acts both in acquisition and tracking. The results of simulations confirm the theoretical work.
