| 摘 要： | 提出了一种新的多个近场窄带信源距离、频率及到达角三维参数的联合估计算法。该算法将通常在数据和子空间域应用的平行因子分析模型扩展至高阶累积量域,利用阵元输出计算的高阶累积量矩阵构造三面阵,分析了该三面阵低秩分解的唯一性,并从分解得到的多个矩阵中联合估计信源距离、频率及到达角。该算法仅需使用3个高阶累积量矩阵,而且无须谱峰搜索和参数配对,计算简单。仿真结果表明该算法是有效的。 |

| Abstract: | A novel joint estimation algorithm for ranges,frequencies and DOAs of multiple near-field narrowband sources is proposed in the near field is proposed. The approach extends the parallel factor(PARAFAC) analysis model from the common data-domain and subspace multiple invariance sensor array(MI-SAP) formulations to the Cumulant one,and forms three-way arrays by using the Cumulant matrices got from array outputs,and analyzes the uniqueness of low-rank decomposition of the three-way arrays,then jointly estimates the ranges,frequencies and DOAs from the matrices via low-rank decomposition.This new method only uses three Cumulant matrices,and doesn't require searching spectral peak or pairing parameters,and is easily implemented.Finally,the simulation results are presented to validate the performance of the proposed method. |
