摘　　要：空时自适应处理(STAP)系统的实现,包括系统任务分配、海量数据的通信和存储,算法模块的并行、映射和调度.针对数据通信在实时系统中是不同节点间的多层次、多速率数据传输的问题,在建立的参数化处理模型基础上,研究了异构STAP系统实现中的不同任务间通信规划方法,讨论了不同通信结构层次对数据通信的影响,并基于粗粒度任务模型实现了四通道STAP系统.实验结果表明,规划的数据通信方案能满足系统的实时处理要求.The implementation of space-time adaptive processing （STAP） system includes the allocation of system tasks, communication and storage of mass data, parallelism, mapping and scheduling of algorithm modules. Concerning for the problem that data communication in real time system is of multi-layer and multi-rate data transmission between various nodes, this paper studies the communication planning between various tasks in implementation of heterogeneous STAP system, discusses the influences of different communication configuration layer on data communication, and realizes a four-channel STAP system based on a coarse-grained task model. Experimental results indicate that the planned data communication scheme could meet the demand of system real time processing.
