| 摘 要： | 本文提出了一种适用于高斯白噪声环境的近场窄带信源定位新算法.该算法利用阵元输出计算的3个二阶统计量矩阵在二阶统计量域构造平行因子分析模型,分析了该模型低秩分解的唯一性,并从其分解得到的多个矩阵中联合估计信源距离、频率及到达角.该算法无须参数配对,无须谱峰搜索,计算简单.仿真结果表明该算法是有效的.

| Abstract: | This paper presents a localization algorithm for near-field narrowband sources in the additive white Gaussian noise environment. Firstly, by use of three second-order statistics (SOS) matrices obtained from array outputs, a parallel factor (PARAFAC) analysis model is constructed in the SOS domain; secondly, the uniqueness of the model's low-rank decomposition is analyzed;thirdly,the range,the frequency,and the direction-of-arrival (DOA) of each source are estimated from the decomposed matrices of the model.The proposed method, which does not really require pairing parameters or searching spectral peaks, can be implemented efficiently.Finally,the simulation results are presented to validate the performance of the proposed method. |
