Faculty Civil Engineering and Geosciences Department Geoscience & Engineering Date 2013-10-01 Abstract Recently, an iterative scheme has been introduced to retrieve the down- and upgoing Green's functions at an arbitrary level ?F inside an acoustic medium as if there were a source at the surface. This scheme requires as input the reflection response acquired at the surface and the direct arrival of the transmission response from the surface to level ?F. The source locations of these Green's functions can be effectively redatumed to level ?F by interferometric redatuming, which requires solving a multidimensional deconvolution problem, essentially being a Fredholm integral equation of the first kind. We show how this problem can be simplified by rewriting it as a Fredholm integral equation of the second kind that can be expanded as a Neumann series. Redatumed data can be used for multiplefree true-amplitude imaging at or in the vicinity of ?F. For imaging the closest reflector to ?F only, the Neumann series can be truncated at the first term without losing accuracy.
