摘要
用单极天线感应外界电场信号设计电光转换电路,信号通过光进行传输,最后通过光电转换,用示波器观察电磁脉冲时域电信号波形。通过时域、频域实验验证,整个系统符合目前核电磁脉冲国际标准的时域和频域要求,有较好信噪比,对相关的电磁脉冲环境研究和电磁兼容研究有重要意义。
In this paper, we report the design and test of a wideband sensor for measuring transient electric field, which is consist of a monopole antenna, high input resistance receiving circuit, electro-optic modulating circuit and fiber links. In the end, a photoelectric conversion is conducted and the E-field signal can be watched on the oscilloscope. Test results show that it can satisfy time-domain and frequency-domain requirements. The sensor may play an important role in the EMP and EMC research.
