摘　　要：基于有色噪声背景下的电磁矢量传感器阵列,提出一种宽带多径循环平稳信号的二维波达方向和极化参数的同时估计算法。该算法充分利用信号的循环平稳特性,不仅解决了宽带多径信号的二维波达方向估计问题,而且具有选择估计信号波达方向的能力。该方法能够抑制有色噪声和宽带干扰的影响。计算机仿真验证了所提方法的有效性。Based on a uniform linear array of electromagnetic vector sensors(EMVS-ULA),a new algorithm was proposed for two-dimension(2-D) direction of arrival(DOA) and polarization of the wideband cyclostationary signals embedded in colored noise under a multipath environment.By sufficiently utilizing the cyclostationarity of the signals,the proposed method not only resolved the problem of 2-D DOA and polarization estimation of wideband sources,but also performed signal selective DOA.The proposed algorithm had the ab...
