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

Abstract: |
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. |
