Characteristics of the Electromagnetic Pulses Radiated from Intracloud Lightning Discharges

The wave shapes of electromagnetic pulses radiated from lightning discharges are significantly changeable one of the topics concerning on EMI/EMC of modern electronic systems is the efficient and economic protection of electronic circuits against transient voltages caused by not only by cloud-to-ground lightning but also by intracloud lightning discharges. In this work, in order to obtain the detailed information about lightning electromagenetic pulses, the electromagnetic pulses radiated from intracloud lightning discharge processes were measured and analyzed statistically.
