摘要：
A subspace-based method is considered to deal with multiple near-field source localisation with a uniform circular array. The property of the centro-symmetric circular array configuration is employed and a matrix which is free of range is constructed. Then, the two-dimensional (2D)-MUSIC method is used to search the 2D angles after the range parameters are separated. After the 2D angles are estimated, a 1D-MUSIC method is used to estimate the corresponding ranges when the estimated 2D angles are substituted into the original form of the received data. It is shown that the proposed method can deal with the case of multiple near-field sources, but with lower computational complexity than that of the available 3D MUSIC method; moreover, the 3D parameters are automatically paired.
