采用分段正弦基函数Galerk in法计算了阵列天线的阻抗矩阵,利用互耦阻抗方程分析了相位加权阵列的幅相恶化程度,且用矩量法分析了互耦对两种相对加权阵列天线性能的影响。提出了一种互耦补偿的方法即网络分析法,仿真结果表明了这种补偿方法的正确性和有效性。

This paper use the subsection sine function Galerkin method to calculate the impedance matrix of the array antenna.Use the mutual coupling impedance equation to analyze the deterioration degree of amplitude and phase for phase weighting arrays antennas.Also,use MOM to analyse the influence of mutual coupling on two kinds phase weighting array antennas.A mutual coupling compensation method is presented.It is network analytical method.The simulation result shows the correctness and validity of this calibration method.
