Q Estimation using Gabor-Morlet Joint Time-Frequency Analysis Techniques

摘要: Summary Two new methods of Q estimation are presented for the first time. Both based on Gabor-Morlet spectral decomposition. They differ substantially from traditional which rely comparison characteristics a shallow time window (approximating seismic wave prior to encountering attenuation) with those deeper (after has been attenuated). Instead, fundamental principle in both is technique each interval determined. We consider two data volumes. The original data, while second after it compensated attenuation effects by use GaborMorlet balancing. assume dispersion can be ignored, course not strictly true because Kramers-Kronig relations then satisfied. However, approximation they give reasonable
