摘要
分析调频连续波方式雷达目标信号处理器的功能、内部结构、工作原理;以DSP和FPGA为核心芯片设计处理电路,构建流水线方式处理数据;FPGA控制低速外设同时内置FIFO数据缓冲;DSP控制FPGA的工作方式,处理采集数据,解算动目标参数;试验表明目标信号处理器的设计具有运行速度快、实时强、工作稳定、可工程化应用的优点,适用于地面动目标跟踪探测。
The function,inner framework and work principle of the signal processor were analyzed based on frequency-modulated continuous-wave radar.The processing circuit of the signal processor was designed by using DSP and FPGA chips as the core part,and the pipeline was built to process data.The FPGA,controlled by the DSP,managed the low peripherals and customized the FIFO data buffer inside;The DSP processed the sampled data and computed the moving target parameter.It has been proved that the signal processor design has the advantage of high speed,real-time processing,and stable working,at same time,can been widely used in ground moving target detection.
