摘要

本文提出了一种基于sc - doa矩阵的二维宽带源到达方向估计方法。理论分析表明，该方法可同时适用于宽带和窄带情况，无需进行二维搜索，且二维参数可自动配对。此外，利用循环平稳性可以消除宽带干扰和加性噪声，从而显著提高了算法的信号检测能力。

A novel method for 2-D spatial spectrum estimation of wideband signals

We propose a new method for two-dimensional direction-of-arrival estimation of wideband sources by constructing a SC-DOA-matrix. The theoretical analysis shows that this method can be applied to both wideband and narrowband cases without any 2D search and that the 2D parameters can be automatically paired. Besides, the wideband interference and additive noise can be mulled out via exploitation of cyclostationarity, thus the signal detection capability of the algorithm is significantly improved.
