Abstract

A new method for estimating spatial narrow-band signal directions of arrival in the presence of colored noise with unknown covariance is presented.An estimate of the noise covariance matrix is given.The data for parameter estimation is then prewhitened using the estimated noise covariance

hence

overcoming the highly biased estimates.Its performances are confirmed by computer simulations.
