基于HHT的连续重力台站背景噪声分析方法研究
RESEARCH ON ANALYSIS METHOD OF BACKGROUND NOISE OF CONTINOUS GRAVITY STATIONS BASED ON HHT
摘要
Abstract
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.关键词
