Abstract

A procedure for estimating of the number and direction of arrival of uncorrelated plane waves in the presence of an unknown colored background noise using a uniform linear array is developed under the assumption that the response of the array to the noise has a rational power spectrum. The number and direction of arrival of the plane waves are estimated by rooting a polynomial which is formed from elements of the vectors spanning the null-space of a Hankel matrix whose entries are the spatial correlation sequence of the sensor outputs. A method for separating the roots of the polynomial that are due to the plane waves from those that are due to the noise is presented.
