Never heard of EV algorithm for DOA estimation? Can you please elaborate?

Khalaf Al-sabaawi

the EigenVector (EV) method have been proposed by Johnson in 1982 for estimation the frequencies of complex exponential in noise. So it can used for DOA estimation.

Well in this case MUSIC is actually based on EV method since the algorithm exploits the noise eigenvector subspace and this is one of the reasons why it is called a DOA subspace method.
