Fpga Automotive Collision Avoidance Radar Signal Processor-based Design And Realization

With the development of economy, the automobile becomes more and more popular, it favors people with advantage, meanwhile, problem on safe become more and more serious. So, people are seeking a way to make the automobile safe, and the development of automobile anti-collision radar become more and more important.In this thesis focused on the study of the automobile anti-collision radar system and the principle, signal processing method of the automobile anti-collision radar is introduced. The main work has been done as follow.(1)Research and development situation of the domestic and foreign automobile anti-collision radar is introduced, and requirements of the automobile anti-collision radar's performance, the principle of work and the system design problems related is discussed. Based on this foundation, the scheme of one kind of the automobile anti-collision radar is proposed.(2)Each component element of the automobile anti-collision radar signal processing, including FFT, the MTD coherent accumulation and the constant false alarm rate (CFAR) detection are studied, and the simulation of the radar echo signal processing is carried out on matlab.(3)Radar signal processing in FPGA is realized with the Xilinx's IP core and VHDL language in Xilinx ISE8.2 software integration environment.
