摘　　要：空时二维自适应处理(STAP)是机载雷达有效抑制杂波和干扰的关键技术,现阶段该技术研究的热点难点之一是大数据流下的高精度实时系统实现问题。本文采用均衡任务处理的方法设计了STAP并行系统,在分析了STAP系统任务特点后,给出了系统任务和任务级的测试基准,基于多DSP异构处理板提出了四通道STAP系统的设计方案并予以实现,系统级测试结果分析表明系统具有较好的均衡性,最后提出几点STAP系统设计实现中的关键问题。Space-time adaptive processing is an important technique used in airborne radar to suppress clutter and jamming effectively. While the serious challenge is the implementation of STAP system with tremendous dataflow and high precision. The STAP system is designed by using the idea of evenly distributing the task loaded across the processors in this paper. Based on the characteristics analysis of the basic tasks of STAP system, the task benchmark and task-level benchmark are given for reference. Then a scheme of four channels STAP system is proposed and implemented with muhi-DSP heterogeneous boards based on the above benchmarks, its system level benchmark is discussed and the results verifies fine system proportionality of the proposed scheme. Many key problems in the design and implementation of STAP system is proposed in the end of the paper for the further study.
