Abstract: The problem is discussed of determining the source coherency structure and estimating the directions of arrival in the presence of coherent signals. The method is closely related to the smoothed rank profile (SRP) algorithm, which shows that for determining the source coherency structure, the number of elements required is greater than or equal to the total number of sources plus the highest degree of signal coherency present. In the modified approach suggested here, it is shown how the SRP method can be augmented by the incorporation of forward-backward averaged covariance to increase the likelihood of the successful determination of the source coherency structure with a limited number of sensors
