基于以太网的雷达数据高速采集与传输技术

Technology of Radar Signal High-speed Acquisition and Transmission with Gigabit Ethernet

本文介绍了基于千兆以太网的雷达数据高速采集与实时传输系统方案。采用FPGA控制数据连续采集并高速缓存到DDR SDRAM中,再通过FPGA内部集成MAC把缓存数据发送到千兆以太网中,实现了对数十兆赫雷达中频回波信号的连续采样和高速网络传输。

This paper introduces a high-speed data acquisition and transmission system with the Gigabit Ethernet, which can support radar echo signal acquisition application. This system uses FPGA to control data acquiring and data buffering, and transfer these buffered data to the DDR SDRAM. Through the MAC integrated in the FPGA, the buffered data in the DDR SDRAM is sent to the Gigabit Ethernet. This system can acquires several decades megahertz radar intermediate frequency echo signal continuously and transfer these acquired data with network high-speedly.
