A fast, explicit wavefield extrapolator based on the GPSPI formula is presented. The central problem of extrapolator stability is presented and addressed by designing two half-step operators with opposing instability. Spatial resampling is described as a very useful imaging tool. Gabor methods can be used to approximate pseudodifferential operators. Gabor wavefield extrapolators, based on an adaptive POU, give promising wavefield extrapolation results.
