Abstract :
A new method is proposed for DOA estimation in the presence of unknown correlated noise fields when the array is linear with equispaced sensors. The proposed method, which employs the modified covariance differencing technique, can efficiently eliminate the effects of correlated noise on the array eigenstructure. The performance of this method is examined using simulations
