摘要

A DSP-based airborne radar universal parallel signal processing system (AUPSPS) is raised to fulfil the universal tasks of high-speed real-time signal processing in airborne radar. This system uses DSP chips as the kernel processor nodes. By means of the private data storage for each node and the pipeline data-flow, it can perform absolutely parallel data processing of multi nodes. This parallel signal processing system has excellent flexibility, universal usage, great throughput, high efficiency of parallel processing, simple structure, small amount of hardware cost and easiness in developing. It can be applied to perform kinds of high-speed real-time signal processing algorithms in airborne or other radars.%针对机载雷达的高速大容量实时信号处理任务，为了提高系统的通用性，提出一种基于DSP芯片的机载雷达通用并行信号处理系统(AUPSPS)设计方案。该系统以DSP芯片为核心处理节点，采用各节点独立存储及数据流水方式实现多DSP的完全并行处理。系统具有通用性和可扩展性好，数据吞吐量大，并行处理效率高，系统结构简单清晰，硬件资源节省，设计开发简便等优点，不但可以灵活适应于机载雷达的各种数据处理算法，而且可应用于其它平台的雷达信号处理机中，实现雷达信号的高速实时并行处理。
