摘要

本文基于均匀圆阵列的特殊结构，提出了一种新的畸变校正算法。在圆阵中心放置近场校准天线，用于估计单元的增益和相位不确定性。此外，利用单远场源估计了到达方向(DoA)和互耦矩阵(MCM)。最后给出了仿真结果，验证了所提方法的有效性。

Mutual coupling calibration for uniform circular array using a single source

In this paper, we propose a novel distortion calibration algorithm for uniform circular array (UCA) based on its special structure. A near-field calibration antenna, located in the center of circular array, is used to estimate the gain and phase uncertainties of elements. Besides, a single far-field source is used to estimate the direction-of-arrival (DoA) and mutual coupling matrix (MCM). Finally, simulation results are given to demonstrate the effectiveness of the proposed method.
