摘　　要：大带宽、多通道信息处理和系统功能灵活软件定义是先进多功能雷达的核心设计要求。针对上述需求,基于遵循OpenVPX标准的国产化开放式全互联处理平台,针对“飞腾”系列国产CPU和“银河麒麟”操作系统的性能特点,设计了具备节点间功能解耦等技术特征的轮询式并行信号处理架构。该架构可有效解决处理节点单点故障导致的信号处理系统失效问题,并可根据功能需求动态灵活地扩展处理资源,因此可显著提升相控阵雷达信号处理系统的可靠性和研制效率。Large bandwidth,multi-channel information processing,and flexible software-defined system functions are the core design requirements of advanced multi-functional radars.In response to the above requirements,based on a domestically produced open fully interconnected processing platform that follows the OpenVPX standard,and according to the performance characteristics of the Feiteng CPUs and the Galaxy Kylin operating system,a polling parallel signal processing architecture is designed with technical features such as functional decoupling between nodes.The failure of signal processing system due to the failure of a single node can be effectively solved,and the resources can be expanded dynamically and flexibly according to functional requirements,significantly improving the reliability and development efficiency of the signal processing system of phased array radars.
