-
摘要: 本文提出了喇叭馈源混合相位中心的一种定义,给出了圆锥喇叭E面和H面混合相位中心的计算公式和相应的优化模型,也给出了求解该模型的快速优化方法,并用该方法对波纹喇叭混合相位中心进行了讨论和计算,还给出了相位中心随观察球面和工作频率的变化规律。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.
