title = "Coherent Signal Classification Using Symmetry Considerations",
abstract = "This correspondence addresses the problem of locating the directions of arrival of a set of coherent/correlated signals in arbitrary noise field using multiple sensor elements. It is shown that by making use of a symmetric array, it is possible to perform a preprocessing on the array output correlations to generate a set of new quantities that are functionally similar to the actual correlations in an incoherent environment. The orthogonality of the direction vectors corresponding to the true angles of arrival and a set of eigenvectors of the Toeplitz matrix generated from these new quantities is then made use of in estimating the actual multipath arrival angles.",

note = "Funding Information: A situation that creates ambiguity with regard to these techniques is the important problem of multipath. where in addition to the direct signal, the sensor array also receives signals from one or several indirect paths. Specific modifications have been suggested to encounter these difficulties, and in particular, the spatial smooth- Manuscript received April 30, 1987: revised June IO. 1988.
