摘　　要：鉴于目前日益复杂的周边空情环境,地面雷达原始视频、点航迹等关键数据的记录存储对于关键空情的事后重演、分析具有关键意义。针对通用雷达数据记录仪与雷达录取终端之间稳定可靠的数据交互需求,文章设计了一种基于国产飞腾CPU的雷达数据记录接口刀片。刀片采用满足VITA46标准的OPEN VPX架构,对外接口包括40 G以太网、SRIO等高速通信接口以及千兆以太网等通用接口,为地面雷达录取终端和雷达通用数据记录仪搭建数据高速交互的桥梁。In view of the increasingly complex surrounding air intelligence environment,the recording and storage of key data such as ground radar original video、point and tracks is crucial for the subsequent replay and analysis of key air conditions.For demand of stable and reliable data interaction between general radar data recorders and radar extracting terminals,this paper develops a radar data recording interface blade based on a domestic Phytium CPU.The blade adopts the VPX architecture which meets the VITA46 standard,and the external interfaces include high-speed communication interfaces such as 40G Ethernet and SRIO,as well as general interfaces such as Gigabit Ethernet,which build a bridge for high-speed data interaction between ground radar extracting terminals and general radar data recorders.
