Abstract：How to extract and analyze phase spectrum information from seismic data effectively will be a hot and difficult point in the frequency domain seismic data processing.We propose in this paper a novel phase reconstruction method based on time-frequency analysis.Firstly, seismic trace time-frequency analysis is carried out.Secondly, seismic trace amplitude and phase information is extracted point by point using windows function.Ater that, phase values to be reconstructed and phase tolerance in[-180°, 180°] are set.Finally, phase reconstructed traces can be obtained after Fourier inverse transform.Model and practical application show tnat the proposed algorithm is accurate and efficient, and beneficial for further applications.
