In this study, at first, a comprehensive review on the Spectral-Based direction-of-arrival (DOA) estimation is presented. We consider both the beamforming and subspace methods of Spectral-Based DOA estimation. The performance, sensitivity to SNR, number of elements, number of snapshots and correlated sources, are compared through the use of plots obtained from several simulations. Moreover, the computational costs of different methods are compared. Subsequently, a new method for DOA estimation is proposed, which offers a better resolution for resolving very closely spaced sources and has a low computational burden.
