摘要: 本文提出了一種基于最小冗余線陣的共軛循環(huán)ESPRIT算法。理論分析和計算機仿真實驗均表明:該算法具有良好的DOA估計性能,增大了陣列孔徑,抗噪能力強,分辨率高,可以用較少的陣元估計更多的信號源方向。計算機仿真實驗驗證了算法的有效性,并比較了該算法與共軛循環(huán)ESPRIT算法的DOA估計性能。

Abstract: In this paper, conjugate cyclic ESPRIT with minimum-redundancy linear-arrays is presented. Theoretical analysis and computer simulation show that the algorithm has better performance, such as extending aperture, being insensitive to noise, having higher resolution, and estimating more sources with fewer sensors. Computer simulation results and comparisons with conjugate cyclic ESPRIT are presented to demonstrate the performance of the proposed algorithm. -
