摘要:

为了满足科研中对雷达信号的采集需求,设计了一种基于FPGA的多通道数据采集系统。该系统涵盖了以太网接口的MAC层、DDR3读写控制、FMC接口的数据接入与控制。系统在经过软硬件联调后,数据采集的各项功能良好,各个通道同步,通道间的串扰较小,可广泛应用与雷达、通信领域。

Abstract:

In order to meet the needs of radar signal acquisition in scientific research,the paper designs a multichannel data acquisition system based on FPGA.The system consists of the Ethernet interface of the MAC layer,DDR3 control of reading and writing,FMC interface of data access and control.Combined test of hardware and software shows that each function of data acquisition is good,and each channel is synchronous with small channel crosstalk.The system can be widely used in radar and communications fields.

Key words: data acquisition;FPGA;Ethernet;DDR3
