摘要

介绍了一种计算小型共形阵列特征高频电磁参数的物理建模方法。该天线阵列模型基于由电小偶极子和环形天线组成的特殊天线单元之间的相互作用，并允许计算天线阵列内部的一般互耦合效应。此外，还描述了一种基于圆柱形扇形波在天线阵列单元上的投影的方向图合成方法。给出了圆柱扇形阵列和常用波束形状阵列的数值结果，并对计算得到的天线阵列内部耦合效应进行了分析。结果与实际天线阵列的实测数据进行了比较。

A polarimetric antenna model for small conformal arrays including mutual coupling effects

A physical modeling method for the calculation of characteristic high-frequency electromagnetic parameters of small conformal arrays is introduced. The antenna array model is based on the interaction between special antenna elements composed of electrically small dipoles and loop antennas and allows for the calculation of generic mutual coupling effects inside the antenna array. Also, a pattern synthesis method based on the projection of cylindrical sector waves onto the antenna array elements is described. Numerical results for arrays of cylindrical sector geometry and commonly used beam shapes are presented and the calculated coupling effects inside the antenna array are analyzed. The results are compared to data measured at a practical antenna array.
