Most exiting array signal processing techniques for direction finding rely heavily on the far-field
assumption. When the sources are located close to the array, these techniques may no longer perform
satisfactorily. In this paper an eigen vector algorithm for 3-D near-field multiple sources localization is
proposed. New algorithm has low computational quantities on 3-D near-field multiple sources localization
by using 2-D near-field multiple sources localization algorithm twice. It also has the properties of high
resolution, low inutile signal-noise ratio threshold and low variance compared with the MUSIC
algorithm.Keywords- near-field sources, eigen vector algorithm 3-D Localization
