Abstract
In this paper, we present a new method called traveltime based reflection full waveform inversion (TT-RFWI) that corrects the kinematic errors between the synthetic and real data. With the new objective function and gradient, the proposed method aims to avoid convergence to local minima with inaccurate initial model and in the meanwhile takes benefits of reflection data. The goal is to provide a deeper reliable low-wavenumber update with reflected energy while missing a good starting background model.
