When is anti-aliasing needed in Kirchhoff migration?
Dimitri Bevc and David E. Lumley
We present criteria to determine when numerical integration
of seismic data will incur operator aliasing. Although there are
many ways to handle operator aliasing, they add expense to the
computational task. This is especially true in three dimensions.
A two-dimensional Kirchhoff migration example illustrates that
the image zone of interest may not always require anti-aliasing and
that considerable cost may be spared by not incorporating it.
