摘　　要：信号处理中阵列信号作为重要的研究方向,在通信、雷达、声纳、地质勘探和电子对抗等领域有广泛的应用,其中空间谱估计是阵列信号的重要分支。为研究多重信号分类算法的目标测向性能,以音频源为例,在均匀圆阵上,对音频源测向的问题进行研究,对算法进行验证后从阵元数、信噪比、波长半径比方面分析了算法性能及其误差,得到这三种参数和算法性能都呈正相关,为后续算法改进研究、应用范围提供方向。As an important research direction in signal processing,array signals have wide applications in fields such as communica⁃tion,radar,sonar,geological exploration,and electronic countermeasures.Among them,spatial spectrum estimation is an important branch of array signals.To study the target direction finding performance of multiple signal classification algorithms,taking audio sources as an example,the problem of audio source direction finding was studied on a uniform circular array.After verifying the algorithm,the al⁃gorithm performance and its errors were analyzed from the aspects of array element number,signal-to-noise ratio,and wavelength radius ratio.It was found that these three parameters are positively correlated with the algorithm performance,providing direction for subsequent algorithm improvement research and application scope.
