Preliminary Investigation of Wavefield Depth Extrapolation by Two-Way Wave Equations

Figure 2

Impulse responses of the two-way phase shift extrapolator in (7) in two-layer models. Left column is for the −50% contrast velocity model (from 2 km/s to 1 km/s); right column is for the +50% contrast velocity model (from 2 km/s to 3 km/s). Rows from top to bottom are for successive of time sequences.
