Measurement and analysis of Electromagnetic Fields Radiated by Corona Discharge

Corona discharge is a usual type of electrostatic discharge (ESD). Electromagnetic fields radiated by corona discharge could be harm to microelectronic devices of airplane and weapon systems. In this paper, corona discharge current is studied in theory and its characteristics are developed by the analysis of measurement data. Moreover, experiment simulation system of corona discharge is built for simulating corona discharge of spatial objects. Further, the characteristics of electromagnetic fields radiated by corona discharge are developed by time-frequency technology and wavelet analysis methods.
