英文摘要：

Intermediate frequency（IF） signal processing device is the core of automotive anti-collision radar system. Aiming at the defects of existing IF signal processing scheme,on the basis of analyses on the tuning requirements of IF radar signal and module functions,an optimization scheme for radar system function is proposed,using multi-functional programmable chip MAX11043. Integrated chip drive is designed based on FPGA technique,with the corresponding time sequential simulation chart obtained. Both simulation and experiment are conducted on the functions of modulated signal generator with the designed drive module. The results of simulation and experiment verify the feasibility of the optimization scheme proposed.
