Deformations of CMP Gathers with v(z) to Hyperbolas
, by Alfonso Gonzalez-Serrano and Jon F. Claerbout
Mapping Snell-traces to Radial-traces, using an approximate velocity function v(z) into ray-tracing equations, provides a practical way of stretching reflection events to hyperbolas, increasing resolution of the velocity-spectrum in CMP gathers.
