摘要
研究了由与坐标轴方向一致的偶极子对构成的均匀线阵。使用四阶累积量提出了一种极化近场源距离、频率及到达角(DOA)三维参数联合估计算法。该算法不需谱峰搜索且各参数自动配对,适用于任意加性高斯噪声环境。仿真结果表明,该算法在性能上优于相应的没有利用极化信息的算法。
An algorithm for jointly estimating range, frequency and DOA of near field narrowband polarized sources with a uniform linear array （ULA） of orthogonal dipole-pair was presented. Without spectral peak searching and paring among parameters, the proposed approach can be employed to arbitrary Gaussian noise environment since the fourth-order cumulant is employed. The simulation results show that by exploiting the source polarization, the proposed method outperforms the conventional method where the polarization information is absent.
