中文摘要：

在任意分布的加性平稳噪声背景下，提出一种基于单个电磁矢量传感器的四阶循环累积量算法来实现宽带循环平稳信号的二维波达方向（DOA）和极化参数估计。通过利用信号的循环平稳特性，使该算法具有信号选择的能力，同时能够抑制宽带干扰和任意分布的加性平稳噪声的影响，从而提高算法的信号检测能力。仿真结果验证了该方法的有效性。

英文摘要：

Based on uni - electromagnetic - vector- sensor,a new fourth- order cyclic cumulation algorithm is proposed for two- dimension （2 - D） Direction of Arrival （DOA） and polarization of the wideband cyclostationary sources embedded in stationary noise with unknown spectral content. By sufficiently utilizing the cyelostationarity of the signals, the proposed method not only performed signal selective DOA, but also suppressed wideband interference and additive stationary noise with unknown spectral content. The signal detection capability is significantly improved. Simulations illustrate the efficiencv of the algorithrn.
