摘要
为了应付电子战复杂电磁环境,具有宽的输入带宽是数字侦察接收机应当满足的必备条件之一。输入带宽越宽,则采样速率和输出的数据率也越高。围绕宽带数字侦察接收机的2个主要环节即高速ADC采集和数据传输,提出并实现了基于高速采样器、大规模FPGA和万兆以太网的高速数据采集传输方案。该方案有效地解决了采样率高达5 Gsps的A/D采样和高流量采样数据实时传输问题。在远程监控终端的控制下,系统完成高速数据采集和传输,具有高度的灵活性和可扩展空间。
To be adapted to the complicated electromagnetic environment of electronic warfare, digital reconnaissance receivers must have wide bandwidth.The wider the bandwidth is,the higher sampling rate and output rate are required[1].On the two topics of wideband digital reconnaissance receiver,that is,high rate sampling and high speed data transfer,the paper proposes and implements a high speed data acquisition and transfer system based on high speed ADC,FPGA and 10Gb Ethernet.The system solves the problem of high rate sampling and high speed data transfer effectively.Finally,under the control of a remote monitoring terminal,the system com-pletes high speed data acquisition and transfer successfully,which shows its good extensibility and flexibility.
