【摘要】 针对现代雷达信号处理功能繁多、运算复杂、数据量大及高速实时处理的要求,设计完成了一种基于新一代DSP芯片和标准CPCI总线的高性能通用雷达并行信号处理系统,该系统以高性能DSP芯片为核心处理节点,采用各节点互联的网状分布式并行处理结构及数据流水处理方式实现多DSP的完全并行处理,已完成的系统结构简单清晰、通用性和可扩展性好,符合雷达信号处理的特点。系统控制计算机可通过标准总线实现灵活方便的系统功能重构和结果获取,使得用户在不改变系统硬件的基础上,完成不同要求的雷达信号处理功能。更多还原

【Abstract】 In this paper,A high-performance radar universal parallel signal processing system based on DSP and CPCI bus is implemented to fulfil the complex data operation and high-speed real-time processing of modern radar.High performance DSP chips are used as the kernel processing nodes.By means of distributed parallel processing architecture with each node interconnection and the pipelined data-flow method.It can perform absolutely parallel data processing of multi-DSP.The finished system is simple in architecture,flexible in scale.The reconfiguration of this system through the standard bus by the embedded control computer make it possible to implement different signal processing tasks without changing the system hardware.更多还原
