The link of Kirchhoff migration and demigration to Kirchhoff and Born modeling

The Kirchhoff approximation provides a representation of seismic data as a summation of imaged data along isochron surfaces (demigration). The asympto tic inversion of this representation provides a migration as a summation of seismic data along diffraction surfaces. We replace Born inversion techniq ues with Kirchhoff inversion techniques and further show the link between t he Kirchhoff and Born representations after the Born linearized reflection coefficient is replaced by the Kirchhoff reflection coefficient.
