Abstract

磁暴是一种重要的地磁场扰动中类型, 影响着通信、电力和航空航天等领域, 因此对磁暴识别技术进行研究与创新有助于磁暴信息的应用. 本文基于2010-2023年12个定点地磁观测水平分量分钟值数据, 采用声谱图成像技术, 运用VGG19卷积神经网络模型开展磁暴日和磁静日人工智能图像分类研究. 实验结果显示, 模型的准确率为97.41%, 精确率为98.00%, 召回率为96.80%, 模型的预测能力较好, 这表明声谱图成像技术在图像识别分类问题中具有较高的实用性, 且VGG19卷积神经网络模型用于 磁暴日和磁静日地磁分类的可行性较高, 研究结果为磁暴预警与监测提供了新的思路.
