| 摘 要： | 介绍了自主研制的脉冲电场原始波形测量系统的模块组成与基本工作原理。针对在未知被测电场方向及复杂的电场环境下垂直干扰电场对自由空间电场测量产生的影响，通过建立自由空间电场测量系统前端的简化模型，对不同尺寸天线与屏蔽盒进行仿真计算。仿真计算结果与理论分析基本一致，结果表明:干扰电场响应信号与待测电场响应信号相差2个数量级以上，干扰电场的影响可忽略不计。

| Abstract: | The paper introduces the original waveform measurement principles for pulsed E-field and the composition of a self-developed E-field sensor, and analyzes the effects of the E-field whose direction of polarization is perpendicular to the direction of monopole on the result of measurement in complicated E-field environments. A simple model of the E-field sensor to analyze the effects of monopoles and shielding boxes different of dimensions.The results of calculation accord with the theoretical analysis. The effect of the E-field whose direction of polarization is perpendicular to the direction of monopole can be ignored, for the response to the interference has an intensity two or more orders of magnitude lower than that to the field to be measured, whose intensity is the sam |
