摘要

针对多片DSP(数字信号处理器)并行处理系统,研究了空时自适应处理(STAP)算法的实时实现.在分析了部分自适应STAP算法内在并行性的基础上,提出了一种任务级的STAP并行处理算法.给出了该算法在多DSP并行处理系统上的算法映射.通过数据实验证明这种基于多DSP并行处理系统的STAP并行算法具有较高的实时性能.

Abstract

Space-time adaptive processing (STAP) technique that is well-known in the area of airborne radars requires very high computing power.In order to meet the real-time requirements in STAP applications,Multi-DSP system is used.In this paper,a method is presented to design parallel algorithms of partially adaptive STAP approaches.Data remapping is used between successive computation steps of STAP.Task level parallelism is used for these steps.As an example,the method is applied to Element space post-Doppler STAP approaches.We also implemented the parallel STAP algorithm on a Multi-DSP system.The effectiveness of our implementation is demonstrated with experimental results.The STAP algorithm is highly signal processing oriented and hence executes efficiently on DSP-based systems.
