提出了一种从任意几何阵列观测中估计多个窄带（NB）源（可能完全相关）到达方向（DOAs）的算法。作为一种预处理器，该算法扩展了NB高分辨率测向方案的应用范围，超出了这些方法在处理相干源时通常假设的线性均匀阵列配置。该方法的新颖之处在于同时考虑了几何因素和最优估计理论的结果
An algorithm is presented for estimating the directions of arrival (DOAs) of multiple narrowband (NB) sources (possible completely correlated) from observations by an array of arbitrary geometry. As a preprocessor, the algorithm extends the application of NB high-resolution direction-finding schemes beyond the linear uniform array configuration, which these methods usually assume when handling coherent sources. The novelty of the approach is that both geometrical considerations and results from optimal estimation theory are used.<<ETX>>
