Aug 9, 2022 · We have developed a curvelet-based joint waveform and envelope inversion (CJWEI) method for inverting imaging near-surface velocity structures.
To understand the long-wavelength recovery by the envelope inversion, we developed a nonlinear seismic signal model, the modulation signal model, as the basis ...
In the full waveform inversion, it is well known that a close initial model is needed when the ultra-low frequencies of data do not exist.
