摘要：

This correspondence is concerned with source localization and classification for scenarios where both the far-field and near-field narrowband sources may coexist. We propose an efficient MUSIC-based solution that requires neither a multidimensional search nor high-order statistics (HOS). We also derive the stochastic Cramer-Rao bound (CRB) for the problem under consideration. The performance of the proposed method is compared with an existing method and with the CRB.
