中文摘要：
概述了阵列测向中的MUSIC算法。分析了该算法在实现过程中各个步骤所占用总运行时间的比例关系．证明了谱峰搜索占用了MUSIC算法的绝大多数时间。提出了3种高效的谱峰搜索算法。根据仿真结论和硬件实测数据设计了应用流水线和数据交织处理并行技术的硬件实现体系结构。最后讨论了两种不同空间谱构造方法对波达方向估计精度的影响．并通过仿真进行了验证。
英文摘要：
Based on summarizing MUSIC algorithm of direction finding, the author analyzes the proportion of every step to the whole run time of the implementation of MUSIC algorithm. It has been proved that peak values searching costs a majority of run time. Thus three kinds of peak values searching algorithms are brought out. According to the result of simulations and testings, the hardware architecture utilizing pipelining and interleaving parallel technologies is designed. At last, the accuracy of DOA estimation using two kinds constructing spatial spectrum is discussed. And the conclusions in this paper are verified by simulation experiments.
