提出一种基于HHT算法的背景噪声分析方法,实验表明该方法较小波分析更好,并研究了如何将HHT方法运用到连续重力台站背景噪声分析中。
This paper introduces a new method based on HHT algorithm to analyze background noise,which is better than Wavelet transform proved by experiments.Besides,this paper studies how to apply the method to background noise analysis of continuous gravity stations and analyzes background noise of the cave stations with same top cover thickness and geological tectonic conditions with the method,as a result,characteristics of background noise is obtained.
