Abstract :
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
