摘　　要：为了实现雷达数据长距离高速可靠传输,该文介绍了基于千兆以太网的雷达数据实时高速可靠传输方案。该方案充分利用了FPGA并行处理、灵活性高的特点,集成实现了两路千兆以太网控制器(MAC),用来并行传输雷达数据,从而提高了数据传输速率;还实现了数据包的校验出错重传机制,确保数据接收端收到正确的数据包,保证了雷达数据的高速长距离可靠传输。In order to implement long distance high-speed reliable transmitting of radar data,this paper introduces a real time high-speed data reliable transmitting system with Gigabit Ethernet. It takes full advantages of the high flexibility and parallel processing ability of FPGA,a double-way Gigabit Ethernet controller was realized in FPGA to parallel transmit radar data,improving the transmitting speed. Also improving the data CRC verify and data re-trans- mitting was implementing in FPGA,and it ensures the receiver getting the right data. So it ensures the long distance high-speed reliable transmitting of radar data.
