| 英文摘要 | To efficiently use the array aperture and avoid the complicated parameter pairing computation, this paper proposes a new cumulant-based algorithm for localizing near-field narrowband sources. firstly, this algorithm proposes a symmetric uniform linear array (ula), and constructs three cumulant matrices by using the fourth-order cumulants of some properly chosen sensor outputs; secondly, unlike the conventional parallel factor (parafac) analysis models in data or subspace domain, it forms a three-way array (twa) in the fourth-order cumulant domain using the three matrices, and analyzes the uniqueness of its low-rank decomposition; thirdly, it jointly estimates the frequency, the direction-of-arrival (doa), and the range of each near-field source from the matrices via the low-rank decomposition of the twa. the simulation results are presented to validate the performance of our proposed method. |
