摘　　要：现有的大地电磁测深信号处理手段并不能唯一、准确地反映大地构造。因此寻找一种新方法处理大地电磁信号,是降低勘探风险的有效措施。采Hilbert-Huang进行功率谱估算,分析了Hilbert-Huang的优越性。对比研究了改进方法与IMAGEM处理对实测数据的处理结果,证实了改进后方法的有效性。Existing magnetotelluric sounding signal processing means not only accurately reflect the tectonic.Therefore, to find a new approach to magnetotelluric signal is an effective measure to reduce exploration risk. In this paper, mining Hilbert-Huang power spectrum estimation, analysis of the superiority of the Hilbert-Huang. Comparative study of the result of the processing of the measured data improved method IMAGEM processing, confirming the effectiveness of the improved method.
