| Abstract: | The paper introduces the composition and functions of radar beacon,puts forward overall design scheme of the intermediate frequency signal processing module.It designs and implements such two core modules as distance delay module and Doppler frequency-shift module based on FPGA.The distance time-delay module is designed by using schematic diagram of QuartusⅡ,and the frequency-shift modulation module is designed based on DSP Builder.The simulation results show that the design scheme of the intermediate frequency signal processing module is perfect and meets the design requirements. |
