Performance of DOA estimation algorithms including mutual coupling

  • 摘要: 研究了考慮互耦情況下的DOA估計(jì)算法MUSIC算法?；ヱ罡淖兞岁嚵许憫?yīng)矢量和接收信號相干矩陣的特征值結(jié)構(gòu),因此影響了DOA估計(jì)的精度,用矩量法計(jì)算了由半波振子陣列的單元之間的互耦,通過得到的阻抗矩陣來估計(jì)互耦的影響。最終給出了計(jì)算機(jī)仿真的結(jié)果。
    Abstract: The effect of mutual coupling among array elements on the performance of MUSIC algorithm is investigated. The presence of mutual coupling distorts array response vector and the eigenstructure of the covariance matrix. The Method of Moment (MoM) is used to evaluate the mutual coupling among the dipoles. The admittance matrix is then used to eliminate the effects of mutual coupling. Finally, the results of computer simulation are given.
