Reflection FWI in MBTT Formulation

Reflection FWI algorithm in Migration Based Travel Time (MBTT) formulation is presented. This approach is based on decomposition of the velocity model for two constituents: smooth propagator and rough depth reflector. Subsequent reformulation of the data misfit function leads to a new FWI statement. Numerical experiments prove the feasibility of reflection FWI in MBTT formulation for macro velocity model reconstruction in case of absence low frequencies in the input data.
