基于Hilbert-Huang变换的室内地磁信号处理分析
|
摘要
提出一种利用Hilbert-Huang变换(HHT)处理分析室内地磁信号的方法。介绍HHT原理与方法,设计出一种室内地磁信号采集平台,对实际测量的室内地磁信号进行经验模态分解(EMD),并对分解后的固有模态函数(IMF)进行频谱和时频剖析,最后将经过HHT处理的原始信号进行重组。结果表明,HHT能用于描述复杂的室内地磁信号的非线性时变特征,为室内地磁信号的处理分析提供一种可行的方法。
A method for processing and analyzing indoor geomagnetic signal using Hilbert-Huang transform( HHT) was proposed. Firstly,the principle and method of HHT was introduced,and an indoor geomagnetic signal acquisition platform was designed. Then the empirical mode decomposition( EMD) was performed on the measured indoor geomagnetic signal,and the spectrum and time-frequency analysis of the decomposed intrinsic mode function( IMF) were performed. Finally,the original signal subjected to HHT processing was recombined. The results show that HHT can be used to describe the nonlinear time-varying characteristics of indoor geomagnetic signal,and provides a feasible method for the processing and analysis of indoor geomagnetic signals.
