摘要
时频域地震资料信息是地震解释的重要依据，本文根据希尔伯特变换、傅立叶分析和小波分析理论提出一种将时域地震信号变换到时频域中去的方法，给出了地震波能量信息与频率关系的直观表示。
Seismic data information in time-frequency domain are the foundation ofseismic interpretation. This paper introduces a method for translating seismic data from timedomain to time-frequency domain based on theories of Hilbert transform. Fourier analysis andwavelet analysis. The relationship between seismic wave energy and its frequencies is given.
