| 摘 要： | 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。

| Abstract: | In general, an accurate mutual coupling correlation is necessary for an array antenna to reach ideal sidelobe level. If the mutual coefficient matrix of an array antenna is perfectly known, one can completely compensate the effect of mutual coupling and realize the desired sidelobe level in theory. However, the mutual coefficient matrix obtained wherever by calculation on by measurement has a limited precision. In this paper, the requirements on the precision of matrix coefficient for compensation in low sidelobe array antenna are discussed. The relationship between mutual coefficient errors and the amplitude and phase errors of channels is derived. |
