电磁喇叭的相位中心研究
ON THE PHASE CENTER OF ELECTROMAGNETIC HORNS
-
摘要: 本文用解析方法研究了具有良好对称性辐射方向图的电磁喇叭的为常数平面的相位中心的性质。证明了,无论是对远场还是对近场情况,=45平面的相位中心与平均相位中心都是一致的。若以单一平面相位中心来近似喇叭的相位中心,=45平面相位中心是一最佳选择。

Abstract: The characteristics of the phase centers of electromagnetic horns holdingnearly symmetric pattern are presented analytically. It is proved that the phase center on the = 45 plane coincides with the average phase center, and if a single plane phase center is used to define the horn phase center approximate y, the = 45 plane phase center will be the best choice. -
