Seismic interferometry (SI) for body waves offers the opportunity to utilize highfrequency scattering coda from local earthquakes to obtain a detailed reflectivity image of the lithosphere. In this thesis it is demonstrated that classical SI methods are seriously affected by circumstances that are typical of field data and that multiple scattering poses a complex trade-off for SI performance. Therefore, we propose an alternative method by multidimensional deconvolution (MDD) that proves to be more resilient under realistic circumstances and properly utilizes the scattering coda: full-field MDD. The main advantage of this method over classical MDD methods is that the kernel of its governing equation is exact, which allows for an optimal use of the multiple scattering coda to obtain virtual primary reflections of the lithosphere.
