The traditional Root-MUSIC algorithm has a weak ability for the extraction of coherent sources. In this paper, an improved forward/backward spatial smoothing Root-MUSIC Algorithm is proposed. By reconstructing and weighting the covariance matrix of the uniform linear array and the subarrays according to certain rules, the modified algorithm could provide a better performance in direction of arrival estimation of coherent sources than the standard. The simulations are given in order to validate the validity of the proposed method.
