Query: Linearized inverse scattering based on seismic Reverse Time Migration   In this paper we study the linearized inverse problem associated with imaging
of reflection seismic data. We introduce an inverse scattering transform
derived from reverse-time migration (RTM). In the process, the explicit
evaluation of the so-called normal operator is avoided, while other
differential and pseudodifferential operator factors are introduced. We prove
that, under certain conditions, the transform yields a partial inverse, and
support this with numerical simulations. In addition, we explain the recently
discussed 'low-frequency artifacts' in RTM, which are naturally removed by the
new method.
