This paper proposes an FPGA-based implementation method for phase-control of two-dimensional phased-array antennas.A phase-control algorithm adapted to the FPGA architecture is obtained by analyzing the phase-control equation of two-dimensional phased-array antennas.The proposed implementation method is capable of performing high-speed phase-control for large-scale two-dimensional phased-array antennas by utilizing abundant memory resources,DSP resources,and parallel computation property of the FPGA chips.Therefore,the proposed method can enable very high-speed scanning of antenna beams in airspace.
