Abstract:
In this paper, a time-domain electromagnetic pulse standard field generation setup was designed and manufactured for transient electromagnetic pulse sensor calibration. The calibration setup is based on the mono-cone structure. It can produce a calculated electromagnetic pulse field with the electric field intensity from 100 V/m to 600 V/m. The quantity of the electric field intensity is traced to the national primary standard of the pulse parameter, the S parameter, and the length quantity. The standard uncertainty of the produced electric field is 2.4%. The waveform and field distribution of the standard field were verified by experiment. Based on this facility, the calibration methods and uncertainty evaluation methods for two types of electromagnetic pulse sensors (TEM horn and D-dot sensor) were proposed. Finally, we obtained the calibration results of the sensors. The standard uncertainties of the calibration are 3.6% for the TEM horn and 3.0% for the D-dot sensor.
