| In this paper, we deal with the problem of localizing mixed far-field (FF)and near-field (NF) sources impinging on a uniform linear arraywith the symmetrical geometric configuration.An efficient method for localization of the mixed FF and NF sources is proposed,where the direction-of-arrivals (DOAs) of the mixed sources are estimated separately by using the oblique projection,and then the ranges of the NF sources are obtained through a polynomial rooting,while the computationally burdensome eigendecomposition and pair-matching are avoided.The effectiveness of the proposed method is verified through numerical examples,and the simulation results show that the proposed method has better estimation performancethan some existing methods. |
