AB  - © 2018 SEG. Full-waveform inversion (FWI) includes both migration and tomography modes. The tomographic component of the gradient from reflections usually is much weaker than the migration component. In order to use the tomography mode of FWI, it is necessary to extract the tomographic component from the gradient. We analyze the characteristics of wavenumbers of the migration and tomographic components, and then introduce a new method to extract the tomographic component based upon non-stationary smoothing. We demonstrate the effectiveness of the proposed method for enhancing the tomographic mode of FWI throughout theoretical analysis and numerical examples.
