Signal resolution using generalized eigenvalues for coherent sources
S. Unnikrishna Pillai · 2003
New results are presented for resolving two or three uncorrelated/coherent plane wave sources in the presence of white noise, when subspace-based high resolution estimators are used to estimate the directions of arrival of incoming signals. The signal to noise ratio required to resolve two or three closely spaced sources is derived in various source scenes. The results are compared with those corresponding to a two uncorrelated/coherent source scene.>
