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.
