A deconvolution inverse scattering imaging condition for RTM separated wavefield imaging

We describe a new imaging condition for reverse-time migration (RTM). Specifically, we extend the inverse scattering imaging condition (ISIC) to deconvolution in the temporal frequency domain, and apply it in an RTM version of Separated Wavefield Imaging (SWIM). Tests on both synthetic and field data show this method successfully removes low-wavenumber artifacts associated with backscattered energy and has similar strengths and challenges to deconvolution-based SWIM with one-way wave equation migration.
