摘要
根据雷电回击理论,在偶极子法的基础上,提出了空间雷电电磁场脉冲(LEMP)强度峰值分布的计算方法,结合实例与DU、TL模型的计算结果进行了比较,验证了本文方法的可靠性,同时研究了雷电流回击速度对LEMP峰值的影响,之后通过雷电电流通道周围空间电磁场的计算与仿真分析,总结了LEMP的分布规律。
Based on lightning return-stroke theory and dipole technique, a method is put forward for calculating spatial distributions of peak values of the lightning electromagnetic pulse （LEMP） intensity this paper, and then its efficient is exhibited by comparing with the results from DU and TL models. After that, the effect of the velocity of lightning return-stroke on LEMP peak value is analyzed and the spaclal distribution of LEMP peak value given by the visual simulation.As a consequence,the distribution characteristic of LEMP is summarized.
