Widespread preprocessing techniques for resolving the coherent source localization problem are the forward-backward averaging and the spatial smoothing [22, 23, 25].
Furthermore, the steering vector of coherent source and noise subspace are not orthogonal anymore and the subspace approaches such as MUSIC do not work well.
With the proposed prior, the DOA estimation for a mixture of uncorrelated and coherent sources is performed under the hierarchical SBI framework using a uniform linear array (ULA).
Section 3 presents the Gauss-Exp-[Chi.sup.2] prior and DOA estimation algorithm for a mixture of uncorrelated and coherent sources within the hierarchical SBI framework.
The d is the distance between center 1 and center 2 and these two centers act as two coherent sources of detached-electron waves emanating from the system after photo detachment.
To see interferences on an observation plane, the distance between two coherent sources should be of the order of wavelength of laser light used.
Vector z amounts to the received data from a coherent source vector b.

The main contributions of the proposed method are as follows: (1) to avoid estimation failure problem using a new antenna configuration and estimate elevation and azimuth angles for coherent sources; (2) to reduce the estimation complexity by constructing Toeplitz data matrices, which are based on a single or few snapshots; and (3) to derive parallel factor (PARAFAC) model to avoid pair-matching problems between multiple sources.
The proposed algorithm assumes noncoherent, coherent, or a mixture of noncoherent and coherent sources to estimate the angles.
