【摘要】 S变换是近年来发展起来的一种时频分析方法,本文首先通过设计理论模型测试S变换对非平稳信号的分辨能力,然后将S变换引入对地震资料随机噪声的压制中去,测试了S变换压制随机噪声的效果.研究表明:S变换是一种有效的时频分析方法,并可以很好地压制叠前地震资料的随机噪声.更多还原

【Abstract】 S transformation is a time-frequency analysis method developed in recent years.In this paper we design models to test its ability to distinguish non-stationary signals,and introduce S transformation into attenuating random noise,and test the effect of S transform in attenuating random noise.The result shows that S transformation is an effective time-frequency analysis method and can work well to attenuate random noise of pre-stack seismic data.更多还原
