    Abstract

    In this paper, a distributed satellite cooperative beamforming algorithm is proposed for the satellite cluster formed by multiple distributed formation flying satellites in the space information network. The average pattern function of distributed formation satellites is derived based on random antenna array theory. On this basis, a multiobjective optimization is formulated to enhance the transmit signal in the desired direction while suppress the interference in the undesired direction via nondominated sorting genetic algorithm II (NSGA-II). The simulation results show that the proposed method extends the distributed and cooperative beamforming technology to the research field of space information network and enhances the electromagnetic wave transceiver capability of resource-constrained satellite systems.
