κ$\kappa$ ‐Generalized Least‐Squares Reverse Time Migration
Least‐squares reverse time migration (LSRTM) is a powerful seismic imaging technique that estimates reflectivity models by iteratively minimizing the discrepancy between observed and modelled data, using the first‐order scattering approximation of the wave equation. However, because LSRTM relies on Gaussian statistical...
