Abstract
Using simulated coda waves, the resolution of the single-scattering model to extract codaQ (Q c ) and its power law frequency dependence was tested. The back-scattering model ofAKI andCHOUET (1975) and the single isotropic-scattering model ofSATO (1977) were examined. The results indicate that: (1) The inputQ c models are reasonably well approximated by the two methods; (2) almost equalQ c values are recovered when the techniques sample the same coda windows; (3) lowQ c models are well estimated in the frequency domain from the early and late part of the coda; and (4) models with highQ c values are more accurately extracted from late code measurements.
