Electric Field Environment Analysis of Near Strike lightning Simulator

When lightning strikes the ground-based weapons, they may experience hazard from either a direct attachment or a nearby lightning. Although direct attachment is the more severe hazard, the indirect effects of a nearby lightning, which may cause a serious safety hazard, should also be paid attention to. For the lightning assessment of these weapons it is necessary to define the electromagnetic (EM) environment near the ground in terms of the magnetic and electric fields and their rates of change at a particular distance from the lightning channel. This paper aims to analysis the electric field environment of the near strike lightning simulator. A verification experiment was tested to validate the simulation, and the result comparison of simulation and experiment was carried out. Furthermore, structural parameters of experiment platform are determined for the subsequent work.
