| 摘 要： | 阵列天线中互耦的存在,严重影响了天线的性能。基于分析天线阵列模型中阵元间的相互关联的特征的方法,构造互耦矩阵C,用C矩阵来修正波达方向估算中的互耦,并在MUSIC算法中实现。理论分析与计算仿真均表明该算法切实可行,有效并易于实现。

| Abstract: | The presence of mutual coupling phenomenon in array antennas affects the performance of the antenna severely. Through analyzing the characteristics among elements, the mutual coupling matrix C is constructed. The matrix C is used to compensate the mutual coupling in DOA estimation, and it is realized by adopting MUSIC algorithm. The method is demonstrated efficient through both theory analysis and simulation. |
