摘　　要：针对目前雷达原始零中频数据后期重新分析的需求,实现低成本的雷达多通道高速数据记录的目的,通过对串行高速输入输出(SRIO)协议三层链路建立过程的分析与实测,设计了基于光纤传输的雷达数据接口,解决了雷达处理机与数据记录卡间Xilinx与Altera两个FPGA厂商SRIO协议互连的问题,以及设计了基于分页DMA控制的PCIe协议接口转换与数据乒乓记录系统,实现了数据传输接口的标准化,实现了高速数据的低成本与高可靠记录。本系统的实现解决了新体制雷达获取实测数据中面临的数据量大、数据通道多、雷达与记录端的远距离传输问题。Aiming at the current requirement for analyzing the radar original zero-intermediate frequency data,it is important to realize rapid data recording for multichannel radar with low cost. By analyzing and actually testing the building process of the3-layer-link for protocol SRIO（ Serial Rapid IO）,the radar data interface based on optical fiber was designed; the interconnection of SRIO protocols from radar processor to data recording card between different FPGA manufacturers Xilinx and Altera was solved,and interface conversion for PCIe protocol and ping-pong data recording system based on paging DMA control were designed,which achieved the normalization of data transmission interfaces and rapid data recording with low cost and high reliability. The accomplishment of this system solved several problems such as mass data,tmultitudinous data channels and remote transmission between the radar and the record end in the acquirement of the measured data for the new system radars.
