Design of radar co-controller based on FPGA

The work cycle of modern radar is shorter and shorter, furthermore, the volume of data that need to be processed becomes larger and larger in a period. It is very difficult for the computer to real-time process large amounts of data and to real-time control radar. This paper proposes designing an FPGA-based co-controller between the computer and radar subsystems, in order to realize the real-time control of the radar. This paper introduces the overall design of the radar co-controller based on FPGA. It comes up with the designs of data buffer memory module, DSP link interface module, radar sub-unit control module and waveform generator control module in VHDL language on QuartusII. The experimental results show that each module of the radar co-controller can meet the requirements, and can correctly process data and command. Design of FPGA-based can obtain application specific radar co-controller chip, and has independent intellectual property rights.
