| 摘 要： | 传统DOA估计算法不能处理多于阵元数的信号源,而且估计精度也不能满足一些高估计精度的场合,近年来基于非圆信号的DOA估计算法由于其优良的估计性能,受到越来越多的关注。依据非圆信号的DOA估计数学模型,研究了基于非圆信号的MUSIC算法。通过软件仿真,将基于非圆信号的MUSIC算法的各项性能进行了仿真。结果表明,该算法的估计性能比传统MUSIC算法有了明显的提高。

| Abstract: | Traditional DOA estimation algorithm can not process signal sources with the number more than sensor number,and its estimation precision can not satisfy the demand of high precision. Recently the DOA estimation algorithm based on noncircular signals has attracted more and more attentions owing to its excellent estimation performance. According to the mathematic model for DOA estimation the MUSIC algorithm based on noncircular signals is researched in the paper. Simulation is executed to analyze the performa... |
