随着毫米波射频传感器在工艺上的突破,毫米波雷达在行业中的应用越来越广泛。为了实现毫米波雷达的高速数据采集,提出一种基于ZYNQ的毫米波雷达高速数据采集系统。该系统面向AWR1243毫米波雷达,基于ZYNQ构建,利用PL和PS软硬件协同工作的灵活性实现雷达自主可控、雷达2.4Gb/s高速CSI2数据解析以及千兆以太网数据上传功能。实验结果表明,该系统运行稳定,千兆以太网数据上传速率高达350Mb/s,丢帧率为零,并且能满足实时性要求。有效解决了已有采集系统成本高、体积大、功能单一、实时性差等问题,为自动驾驶、无人机避障、手势识别等应用提供了一套低成本、小体积、易操作的数据采集系统。

With the breakthrough of the millimeter wave radio frequency sensor in technology,the millimeter wave radar is more and more widely used in the industry.A ZYNQ-based high-speed data acquisition system for millimeter wave radar is pro-posed to realize its high-speed data acquisition.The system designed for AWR1243 millimeter wave radar can realize functions of radar autonomous controllability,radar 2.4 Gb/s CSI2 data analysis and Gigabit Ethernet data uploading by the flexibility of software and hardware cooperative work using PL and PS.The experimental results show that the system proposed in this paper runs stably,its data upload rate in gigabit Ethernet reaches up to 350 Mb/s,its frame loss rate is zero,which can meet real time requirement.The system effectively solves the problems of high cost,large volume,single function and poor real-time per-formance of existing in acquisition systems,and provides a low-cost,small-volume,easy-to-operate data acquisition system for applications such as automatic driving,drone avoidance,and gesture recognition.
