基于光纤技术的雷达高速通信技术研究

摘要

文章分析了雷达高速宽带数字接收与恢复的现状,以及制约其发展的关键因素,提出基于高速串行器/解串器、FPGA和正交数字上变频器的高速宽带数字接收与恢复系统方案.系统以光纤为传输媒介,以FPGA为控制核心,正交调试器为信号调制平台,完成高速数字接收、基带信号预处理与基带信号的上变频等功能.该系统具有误码率低、可靠性高的优点.%This paper analyzes radar high-speed broadband digital receiver status and recovery,as well as the key factor of restricting its development,proposed high-speed broadband digital high-speed serializer/deserializer,FPGA and quadrature digital upconverter reception and recovery system based on.The system uses optical fiber as the transmission medium,using FPGA as the control core,the debugger for orthogonal signal modulation platform,high-speed digital receiver,baseband signal pretreatment and baseband signal function of frequency.This system has the advantages of low reliability,high bit error rate.
