Abstract :
Two different approaches for estimating the direction of arrival (DOA) of two coherent signals impinging on a uniform linear array are analyzed. Simple asymptotic expressions for the variance as well as for the bias of the estimated angles are derived. The simplicity of the method allows much insight and an easy analytic comparison is achieved. Examples are also provided
