| 摘 要： | 本文设计了一种时域天线,具有超宽带特性,在频带范围内天线端口反射系数小于-10dB（VSWR〈2）,可以确保电磁脉冲测量的不失真。并且在脉冲测量中用了一种对此时域天线的新的分析方法,即引入了转移函数。根据现有理论可以计算出测量系统所用的同轴传输线的损耗。最后利用宽带示波器显示的测量信号的结果,通过此显示的信号能很容易的计算出需要测量的脉冲信号。

| Abstract: | The paper introduces a designed time domain antenna which can make the measuring electromagnetic impulse signal not distorted.And the transfer function is also introduced as a new method to analyze and to measure the electromagnetic impulse.The loss of the coaxial transmission line can be obtained according to current theories.At last a broadband oscilloscope will show the signal which can be used to calculate the measuring impulse signal easily. |
