Estimation of the directions of arrival of signals in unknown correlated noise. II. Asymptotic behavior and performance of the MAP approach

摘要

For pt.I see ibid., vol.40, no.8, p.2007-17 (1992). The asymptotic behavior and the statistical performance of the maximum a posteriori (MAP) estimate of the directions of arrival (DOAs) of signals applicable in an environment where the sensor noise is unknown and correlated. Computer simulations were performed to confirm the correctness of the performance analysis, and a comparison of the performance of the MAP estimate with other methods is also presented.
