摘要
本文提出了一种基于四阶累积量的ESPRIT超分辨阵列测向算法,该算法适用于任意形状排列的空间阵列。通过对误差模型的分析,发现该算法具有稳健性,只要接收通道中任意两个通道能保持一致,该算法就能得到正确的方向估计。计算机模拟验证了该算法的正确性。
In this paper, a fourth-order cumulant-based ESPRIT DOA estimation method is presented for arbitrary array. The method is robust to the channel uncertainty model errors with any two channels' characteristics known. The method is verified by the simulation experiments.
