【摘要】 本文主要介绍了一种雷击通道模型,该通道模型既具有雷电的特性,又具有简洁的数学表达式。本模型通过计算电磁学手段计算出多个频点该雷击通道产生的频域电磁场,再利用反傅里叶变换得到其时域结果,回代到矩量法中,观察雷击通道周围的近场分布。文中给出一个实际案例进行结果说明,证明方法准确可靠。更多还原

【Abstract】 This article mainly introduces a new type of lightning strike channel model,which not only has the characteristics of thunder and lightning,but also has simple mathematical expressions.This model uses computational electromagnetics to calculate the frequency domain electromagnetic field generated by the lightning channel at multiple frequency points,and then uses the inverse Fourier transform to obtain the time domain result,which is substituted into the method of moments to observe the RCS on the target surface.An actual case is given to illustrate the results,which proves that the method is accurate and reliable.更多还原
