摘要
结合具体的雷达导引头型号项目,从数字信号处理机的原理出发,根据项目的要求提出了一种基于DBF技术的某型导引头信号处理机设计方案,方案以Xilinx公司Virtex4SX55FPGA作为数字信号处理的核心器件,实现对6阵元阵列天线接收的回波信号进行实时采集和处理。对系统硬件和软件总体设计及基频信号产生模块、回波信号采集模块、控制信号产生模块和时钟电路模块的具体设计进行了详细介绍。最后在暗室环境对系统进行了测试,测试结果表明系统达到了设计要求。
Based on engineering project of radar seeker and the principle of digital signal processor,a blue print including DBF technology is proposed to match the requirement of the project.The hardware design was accomplished.Xilinx Virtex4 SX55 FPGA was selected as the key instrument.The design of baseband signal generation module,the echo signal acquisition module,the control signal generation module and the clock circuit are deeply introduced.The digital radar signal processor was tested in dark house.The results show that the performance of the design matches the requirement of the radar signal processor.
