A radar echoes pre-processing module based on COM Express was designed to met with the rebuild need of data processing platform which is used in shipborne radar. The echoes data receiving bottle-neck of radar system is solved by moving the radarechoes pre-processing function to the interface board, which adjusted the implementation of data processing platform and its software. The paper analyses the rebuild need of data processing platform, described the design plan of the module, the hardware design, the signal flow of echoes data as well as the driver of PEX8311 chip in Vxworks operating system. The module highly improved the processing ability of radar echoes data, witch can receive and process the radar echoes data correctly even in extremelyhard station, so it met the need with the rebuild need of radar data processing platform.

摘要:

为实现声纳数据的海量实时存储,提出一种基于COM Express架构的数据记录仪的设计与实现方法。该记录仪在COM Express载板上集成了ETXexpress处理器模块、光纤数据采集子卡,以及由4个500 GB硬盘组成的RAID0存储阵列。应用结果表明,该记录仪可以达到80 MB/s以上的实时存储速率,很好地胜任了声纳数据的存储任务。
