摘要
针对宽带线型调频(WLFM)信号空间谱估计(special spectrum estimation)运算量大的弊端,研究了模糊函数域-空域处理算法的实时实现。在分析了算法内在并行性的基础上,提出了一种任务级的并行处理算法。给出了该算法在多数字信号处理器(DSP)并行处理系统上的算法映射。数据实验结果表明,基于多DSP并行处理系统的模糊函数域-空域并行算法具有较高的实时性能。
Aimed at the abuse of a mass of operation of special spectrum estimation of WLFM, the real-time realization of algorithm dealing with ambiguity function-space is researched. On the basis of analyzing the inside parallel of algorithm, a kind of parallel processing algorithm of task leveled is put forward. The mapped of algorithm on multi-DSP parallel processing system is given. By the way of data experiment, the ambiguity function-space parallel processing algorithm based on multi-DSP parallel processing system is proven that it has upper real-time capability.
