摘要：
We analyzed the measurement principle of pulse electric field with small monopole antenna, and studied the influences of antenna impedance and load impedance on the measurement index based on the equivalent circuit model. A wide band pulse electric field measurement system was designed with FET amplifier as the core device. To solve the problem that the sensitivity of the measurement system is not constant due to the change of optical power in the transmission link, the sensitivity coefficient of the measurement system was self-calibrated in real time by the integrated controllable standard square wave. Based on power management, the distortion of optical pulse waveform caused by the heating of semiconductor laser nodules was overcome. The influence of the field enhancement effect caused by the detector shell in TEM cell was discussed, and a reasonable correction method was given. The calibration results show that the system can measure the pulse front ≥600 ps, the pulse width ≤1 ms, and the dynamic range of measurement is 40 dB. Based on the combination of several measurement systems under different sensitivity coefficients, the range coverage of ±0.5 V/m~ 200 kV /m can be achieved, and it can meet the requirements of measurements for high altitude electromagnetic pulse, high-altitude electromagnetic pulse and electrostatic discharge electromagnetic pulse. © 2021, High Voltage Engineering Editorial Department of CEPRI.
