摘要

A Bayesian high-resolution direction-of-arrival (DOA) estimator is proposed based on the maximum a posteriori principle. The statistical performance of the Bayesian highresolution DOA estimator is also investigated. Comparison with MUSIC and Maximum likelihood estimator (MLE) shows that the Bayesian method has higher resolution and more accurate estimates for either incoherent or coherent sources. It is also more robust in the case of low SNR.
