摘要: 本文提出了喇叭饋源混合相位中心的一種定義,給出了圓錐喇叭E面和H面混合相位中心的計算公式和相應的優(yōu)化模型,也給出了求解該模型的快速優(yōu)化方法,并用該方法對波紋喇叭混合相位中心進行了討論和計算,還給出了相位中心隨觀察球面和工作頻率的變化規(guī)律。

Abstract: A definition of combined phase centre for conical horn feeds is given. Formulas of E-plane and H-plane combined phase centre for conical horns and the corres-ponding optimal model are presented, and a fast optimization method for solving this model is given. By using this method, the phase centre corrugated horn with reference to operating frequencies and distances is discussed. -
