基于四阶累积量和ＥＳＰＲＩＴ算法提出了一种新的任意高斯噪声环境下多个独立空间信号二维到达角和极化的联合估计方法。该算法的阵列由和坐标轴方向一致的偶极子对组成，各偶极子对的排列结构任意。通过巧妙定义阵列输出四阶累积量矩阵，并运用四阶累积量的特性，该算法与已有的基于二阶统计的方法结合起来。计算机模拟结果证实了方法的可行性。
Based on the fourth-order cumulant and ESPRIT algorithm, a new joint estimation method of two-dimensional angle of arrival and polarization of multiple independent spatial signals under arbitrary Gaussian noise environment is proposed. The array of the algorithm consists of a dipole pair that coincides with the direction of the coordinate axis, and the arrangement of the dipole pairs is arbitrary. By cleverly defining the array to output the fourth-order cumulant matrix and using the characteristics of fourth-order cumulants, the algorithm is combined with the existing second-order statistics based method. Computer simulation results confirm the feasibility of the method.
