An improved method for Q-factor estimates based on the frequency-weighted-exponential function
C Li, X Liu - Journal of Applied Geophysics, 2016 - Elsevier
The frequency-weighted-exponential (FWE) function was designed to fit asymmetric
amplitude spectra by two parameters: symmetry index and bandwidth factor. It was applied
to Q-factor estimates by fitting the amplitude spectra of source and attenuated wavelet. This
method for Q-factor estimates was called the FWE method. The accuracy of the Q-factor
estimates by the FWE method depends on the similarity between the modeled FWE
functions and the amplitude spectra of source and attenuated wavelet. However, the …
