To incorporate the dip effect, Huub Den Rooijen (1991) transforms data
from CMP-sorted data to CCP-sorted data using a
dip moveout operator. Like the PP-DMO, PS-DMO
may reduce the problem of reflection point dispersal due to reflector dip without
knowledge of the reflector geometry. Most of the existing PS-DMO
operators give errors due to truncation of power series and/or
second order approximations Xu et al. (2001). Xu et al. (2001) shows
a fast converted-wave dip moveout operator in the f-k log-stretch domain which partially
alleviates approximation errors. His operator correctly handles
the kinematics, but produces weak amplitudes for steeply dipping reflectors
at high propagation angles. Throughout this section I present a review
of the operator developed by Xu et al. (2001) operator and extend it to correctly handle
high propagation angles for steeply dipping reflectors.
