摘要： 高空电磁脉冲环境计算为电磁脉冲效应技术研究和防护加固等提供环境基础。为了快速计算高空电磁脉冲环境参数及其分布,研究了一种物理计算方法与机器学习相结合的方法。该方法首先利用高空电磁脉冲的数值模拟方法计算出不同爆高、不同γ当量、空间不同位置的高空电磁脉冲离散数据,再使用机器学习中的神经网络方法建立多参数快速计算模型,最后根据建立的快速计算模型,并行批量计算一定范围内任意不同爆高、不同当量、空间不同位置地面附近的高空电磁脉冲环境参数,并快速计算推导高空电磁脉冲在地面附近的场分布。结果表明,该方法在保证计算精度的同时,可以极大加快计算速度,可以为高空电磁脉冲传导环境计算提供所需的大量入射场参数。
