A Bayesian approach to high-resolution direction-of-arrival estimation

Improvement of performance and robustness of high-resolution DOA estimators continues to be a problem of significant interest. In this paper, a method for estimation of DOA of multiple sources based on Bayes theory is presented. Its performance is demonstrated by simulations whose results show that the resolution achieved by the Bayesian approach is much superior to that obtained by MUSIC and other standard algorithms for high-resolution DOA estimation.
