摘要 基于特殊天线阵列,提出了一种有相干源存在情况下的二维波达方向(DOA)估计的新方法。该方法利用天线阵列结构的特点来构建一个特殊的协方差矩阵,再根据2-D ESPRIT方法实现二维DOA估计。该方法不需采用空间平滑技术,也不需谱峰搜索,而且参数可以实现自动配对。最后计算机仿真验证了该方法的有效性。 This paper presents a new method for estimating two-dimensional (2-D) direction-of-arrival (DOA) in coherent source environment with a special array. The method constructs a special covariance matrix using the characteristic of the array. Then the DOA can be estimated according to the 2-D ESPRIT method. The method needn't the spatial smoothing techniques and spectral peak searching, and estimates are automatically paired. The computer simulation indicates that the method is effective.
