本文提出了一种基于迭代的联合增益/相位和互耦合阵列校准方法。它利用阵列的波束方向图特性形成的一组联立方程来估计阵列增益/相位和互耦合系数。只需要一个方向已知的校准源即可获得唯一的估计值。仿真结果和在高频无线电频段工作的天线阵列收集的实验数据说明了该方法的有效性。
An iterative-based method for joint gain/phase and mutual coupling array calibration is proposed in this paper. It estimates the array gain/phase and mutual coupling coefficients with a set of simultaneous equations formed by using the beam pattern property of the array. Only one calibrating source with known direction is requiblue to obtain the unique estimate. The effectiveness of this approach is illustrated by simulation results and by experimental data collected with an antenna array operating in high-frequency radio band.
