| Abstract: | To meet the requirement of rocket-berne conformal phased array antennas used in space-based TT＆C for beam steering, the design requirement and task of rocket-berne antenna beam steering system is analyzed, the basic principle of plane phased array antenna beam steering system is introduced, and based on which a rocket-borne conformal phased array antenna beam steering algorithm based on array factor function is deduced. A centralized beam steering system based on table lookup is proposed to meet the requirement of space-based Tr＆c of carrier rocket, and the system design method is given. The results of prototype testing show that the designed beam steering system meet the requirement of rocket-berne conformal phased array antenna. |
