Theoretical background for continental-and global-scale full-waveform inversion in the time-frequency domain

Fichtner, Andreas; Kennett, Brian; Igel, Heiner; Bunge, Hans-Peter

Description

We propose a new approach to full seismic waveform inversion on continental and global scales. This is based on the time-frequency transform of both data and synthetic seismograms with the use of time- and frequency-dependent phase and envelope misfits. These misfits allow us to provide a complete quantification of the differences between data and synthetics while separating phase and amplitude information. The result is an efficient exploitation of waveform information that is robust and...[Show more]
