Q-factor Estimation Method Based on Time-varying Wavelet by Daming GE, Jianguo SONG

“…It calculates the quality factor Q based on the linear relationship between the logarithmic spectral ratio of seismic wavelets at different times and the Q value. The core idea of the time-frequency domain spectral ratio method is to extract the spectral distribution at different moments via time-frequency spectrum analysis, representing the frequency spectrum of seismic wavelets at those moments while ignoring the influence of reflection coefficients. …”
