Asymptotic Analysis of Differential Semblance for Layered Acoustics
Symes, William W.
Differential semblance velocity estimators have well-defined and smooth high frequency asymptotics. A version appropriate for analysis of CMP gathers and layered acoustic models has no secondary minima within a sublevel set of velocity profiles, independent of data frequency content, unlike other estimators such as stack power and output least squares. The sublevel set is characterized by the interaction between reflector density and velocity variability.
