基于多重信号分类算法的目标测向性能及误差分析
Target direction finding performance and error analysis based on multiple signal classification algorithms
摘要
Abstract
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.关键词
