摘要: 本文提出了一種基于四階累積量的ESPRIT超分辨陣列測(cè)向算法,該算法適用于任意形狀排列的空間陣列。通過對(duì)誤差模型的分析,發(fā)現(xiàn)該算法具有穩(wěn)健性,只要接收通道中任意兩個(gè)通道能保持一致,該算法就能得到正確的方向估計(jì)。計(jì)算機(jī)模擬驗(yàn)證了該算法的正確性。

Abstract: 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. -
