摘要
在雷电电磁场理论的基础上,计算出雷电流产生的电场强度和磁场强度方程。采用传输线模型(TL)对雷电流电磁场进行计算,得出了雷电电磁脉冲的近场和远场与雷电通道底部电流的关系式,结合脉冲函数仿真了雷电通道底部电流在空间中产生的电磁场。
Electric field and magnetic field intensity equations of lightning current producing are calculated based on lightning electromagnetic field theory. Electromagnetic field of lightning current is computed by Transmission Line model （TL）, which obtained relation formula of near-field and far-field of the lightning electromagnetic impulse and the bottom current of lightning channel, it combined with the pulse function simulation electromagnetic field of the bottom current of lightning channel generated in spaee.
