摘要
基于宽带点源入射波的阵列输出相关矩阵与窄带分布源入射波的阵列输出相关矩阵的结构相似性 ,论文提出了可利用窄带分布源角度估计技术估计宽带点源到达角的新方法 ,并给出了协方差匹配技术处理宽带点源的算法和仿真 .仿真结果证实新方法有效性 .
Based on the structural analogy of the correlation matrixes of array output from a broadband point source and a narrowband distributed source, a new approach is presented which utilizes a DOA estimation approach of a narrowband distributed source to estimate the DOA of a broadband point source. The covariance matching technique to process a broadband point source and some simulations are given. The results of the simulations verify show the analysis is effective.
