| 英文摘要 | This paper proposes a new cumulant-based algorithm to jointly estimate four- dimensional (4d) source parameters of multiple near-field narrowband sources. firstly, this approach proposes a new cross-array, and constructs five high-dimensional toeplitz matrices using the fourth-order cumulants of some properly chosen sensor outputs; secondly, it forms a parallel factor (parafac) model in the cumulant domain using these matrices, and analyzes the unique low-rank decomposition of this model; thirdly, it jointly estimates the frequency, two-dimensional (2d) directions-of-arrival (doas), and range of each near-field source from the matrices via the low-rank three-way array (twa) decomposition. in comparison with some available methods, the proposed algorithm, which efficiently makes use of the array aperture, can localize n - 3 sources using n sensors. in addition, it requires neither pairing parameters nor multidimensional search. simulation results are presented to validate the performance of the proposed method. copyright (c) 2007 junli liang et al. |
