| 摘 要： | 该文利用广州高建筑物雷电观测站架设完成的一套正交磁环天线,对广州珠江新城高建筑物群进行地闪水平磁场观测。采用小波软阈值去噪法和基础噪声归零法对合成的磁场数据进行质量控制。对处理后的水平磁场波形进行频谱特征分析,得到水平磁场在不同频段内的能量分布情况,为高建筑物雷电强电磁脉冲屏蔽防护技术提供数据参考。

| Abstract: | The Tall-Object Lightning Observatory in Guangzhou(TOLOG) could technically observes lightning flashes striking on tall objects with different heights in Pearl River New City of guangzhou.Horizontal magnetic field of cloud-to-ground lightning data obtained by orthogonal-loop magnetic antenna. The soft-threshold wavelet denoising method and the basic noise zero method were used for data preprocessing. Through spectrum feature analysis, the energy distribution of horizontal magnetic field in different frequency bands is obtained.The research results can provide reference data for strong electromagnetic pulse protection technique of tall building. |
