从天线阵列互耦补偿的理论出发 ,导出了互耦系数误差与接收通道幅相误差的等效关系 .理论分析表明 ,互耦系数误差引起的通道幅相误差与阵列单元数和互耦系数的方差成正比 ;利用互耦系数矩阵能补偿因互耦造成的误差 ,但补偿效果依赖于互耦系数的精度 ,要实现低副瓣并有效地进行互耦补偿 ,必须准确测量或计算出天线阵的互耦系数 .
Based on the theory of mutual compensation of antenna array, the equivalent relationship between the mutual coupling coefficient error and the amplitude and phase error of the receiving channel is deduced.Theoretical analysis shows that the amplitude and phase error of the channel caused by mutual coupling coefficient error and the number of array elements and mutual coupling coefficient Variance is proportional to; mutual coupling coefficient matrix can be used to compensate for the error caused by mutual coupling, but the compensation effect depends on the mutual coupling coefficient accuracy, to achieve low side lobe and effective mutual coupling compensation, we must accurately measure or calculate the antenna array Mutual coupling coefficient.
