摘要
文章简述了智能天线的基本原理 ,并对智能天线的工作基础 :波达方向估计进行了讨论 .通过建模与仿真 ,用波达方向估计的 3种方法 :延迟相加、最小方差无畸变响应 (Capon) ,多重信号分类 (Music) ,分别对来自不同方向的 4个信号利 5个信号进入 8个阵元的等距离圆天线阵列进行试验 。
The intelligent antenna's fundamental principles and DOA' estimation of the intelligent antenna's groundwork are briefly presented. By mean of structure model and simulation, three basic methods of DOA' estimation are illustrated: conventional technique, Minimum Variance Distortion-less Response (Capon), Multiple signal classification (Music). Simulated test is respectively conducted on the antenna array with four and five signals from different directions entering eight elements of UCA so that the results and maximum resolving ability are gained.
