| In this paper, we consider the source localizationfor the multiple near-field narrowband signals impinging on a symmetricuniform linear array (ULA) in nonuniform noise. We introduce the matrix completion (MC) approach to reconstruct the noise-freecovariance matrix for estimating the signal subspace. Then, some existingsource localization methods can be applied immediately. Finally, the effectivenessof the proposed method is verified through numerical examples. |
