摘　　要：针对雷达IQ光纤数据流高速、实时传输的问题,基于Stratix II GX系列高性能FPGA和CPCI标准总线等硬件设备,采用数据率自动判别、乒乓缓存和计算机实时中断处理等关键技术,设计了一种雷达IQ光纤数据采集及传输系统。介绍了系统的组成和设计原理,并对系统的硬件、FPGA和软件设计进行了描述。经实际工程验证,该数据采集及传输系统性能稳定。In view of the high-speed and real-time transmission problem of radar IQ fiber-optic data stream,a radar IQ Fiber-optical data acquisition and transmission system is designed based on the Stratix II GX series FPGA,the CPCI international standard bus and other hardware devices. Some key technologies such as data rate automatic identification,ping-pang cache,real-time interrupt processing are applied in this system. Emphasis is put on the structure of the data acquisition and transmission system and its design principle. Hardware design,FPGA design and software design are also introduced. Experiments results show that this system has stable performance.
