摘要
针对目前声纳接收机小型化,功能集成化的发展趋势,本文设计了一套声纳接收机控制传输系统。系统通过利用一块高性能FPGA完成多通道同步控制、信号预处理与海量数据实时传输,通过千兆以太网与上位机进行数据交互,实时响应上位机下发的控制指令,调整工作状态,根据指令要求对接收信号进行TVG增益补偿,输出响应延时在3.5us以内。通过对多路ADC同步采集,将回波信号进行预处理、降采样后,通过千兆以太网MAC核打包上传至上位机进行后续处理,上行数据链最高传输速度可达367Mbps,延迟在1.2us以内。
In this paper, a control transmission system in sonar receiver is designed to meet the current trend of miniaturization and function integration in underwater part of sonar. The system achieves simultaneous control of multiple channels, preprocess of signals and real-time transmission of mass data with a high-performance FPGA. With data switching to host computer via gigabit Ethernet, control commands issued by host computer can be responded in real-time, therefor adjusting the working state. By performing TVG gain compensation on received signals in compliance with the commands, the delay of output can be confined to a 3.5us range. After simultaneously sampling from multiple ADCs, preprocessing and down sampling echo signals, generated data will be packaged and uploaded to host computer via MAC core of gigabit Ethernet for subsequent procedure, while the transmission rate of up streaming data link can reach 367 Mbps as the highest, and a time-delay under 1.2us.
