A UNIFIED BORN-KIRCHHOFF REPRESENTATION FOR ACOUSTIC MEDIA

For the modeling of a single-target reflector in a smooth inhomogeneou s elastic anisotropic medium, it has been recently shown that the volu me Born integral can be transformed into a surface-scattering integral on the reflector. This derived surface integral has been called Born- Kirchhoff as it relates very naturally to the Kirchhoff-Helmholtz inte gral, thus providing the theoretical link between the two approaches. Here we specify the derivation and main properties of the Born-Kirchho ff integral in the acoustic case, and use a simple synthetic example t o provide a comparison between the new integral and its classical coun terparts.
