Abstract :
The calibration of field distribution in EMP simulator is discussed. A small size dipole sensor with built-in optic transmitter and fiber optic output connection is designed to measure field distribution in various points of the EMP simulator. Influence of the dipole sensor to the field distribution is first analyzed by numerical simulation and the actual field distribution is measured by the dipole. A correction coefficient is proposed based on the measurement results. The available working space in EMP simulator for sensor calibration is also defined.
