Preliminary Investigation of Wavefield Depth Extrapolation by Two-Way Wave Equations
Figure 5
Impulse responses of the two-way beamlet propagator 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.
