高保真超宽带TEM嗽叭的分析与设计

Analysis and Design of UWB TEM Horn with Waveform High Fidelity

本文讨论了波形保真的ＴＥＭ嗽叭分析和设计问题．本文提出了两个新论点：１）嗽叭的开口端阻抗不能看作真空波阻抗，它与嗽叭尺寸、张角有关；２）冲激脉冲有时序性能，反射只与局部结构有关，因此，波形保真嗽叭不同于普通的宽带嗽叭．本文按此思想设计了一个宽张角圆锥ＴＥＮ嗽叭，实验表明波形保真良好．

The TEM horn for transmitting and receiving narrow pulse or impulse waveform has been discussed in this paper. A novel design concept and calculation method have been presented. According to this concept, a ridged conical TEM horn has been designed and fabricated. The experiment results show that its performance is excellent.so it is very valuable for the study of transient field and ultrawideband (UWB) radar
