摘　　要：空时自适应处理(STAP)是新一代机载信号处理机的关键技术之一,它对系统的实时性有严格的要求。在分析实时STAP性能需求的基础上,利用基于TS201的高性能数字信号处理板,实现了一个STAP并行处理系统。结合STAP处理特点和系统体系结构,提出了一个局部串行全局并行的系统算法模型,并在模型实现中采用了高效的通信与同步方法。该模型有效的增强了系统的负载平衡特性。实测结果表明,系统满足STAP处理实时要求,并且有很好的可扩展特性。Space-time adaptive processing （STAP）, which is the key technology of airborne digital signal processing system, requires rigorous real-time constraints. Based on requirements of real-time STAP, a parallel processing system is realized for STAP, and it is composed of high-performance digital signal processing boards based on TS201. Through analyzing characteristics of STAP and system architecture, a system algorithmic model which is local serial and global parallel is presented, and high efficient ways are adopted for communication and synchronization during the course of model development. This model effectively enhances capability of load equalization for system. This system meet the real-time requirements and has good scalability. Key words：
