| 中文摘要: |
| 为了精确采集前端雷达信号,设计了一种基于现场可编程逻辑门阵列(field programmable gate array,FPGA)的雷达采集系统。采用FPGA作为核心主控芯片,通过给雷达收发芯片赋值产生雷达信号,用FPGA控制板间的AD芯片对回波信号进行采样。最后将信号传输到上位机中,从而实现雷达信号获取、数据采集控制、数据缓存、数据传输以及时钟同步控制等功能。实验结果表明,该系统达到了设计要求且具有易携带、成本低、构造简单、可靠性强、速率快等特点,经过该系统采集的信号可用于对实际场景下物体速度、距离的解析。 |

| In order to acquire front-end radar signal accurately, a radar acquisition system based on field programmable gate array(FPGA) is designed. FPGA is used as the core control chip. The radar signal is generated by assigning a value to the radar transceiver chip. The AD chip between FPGA control boards samples the echo signal, and finally transmits the signal to the host computer, so as to realize the functions of radar signal acquisition, data acquisition control, data cache, data transmission and clock synchronization control. The experimental results show that the system meets the design requirements, and has the characteristics of easy-to-carry, low cost, simple structure, strong reliability and fast speed. The signals collected by the system can be used to analyze the speed and distance of objects in the actual scene. |
