Well-posed Questions for Ill-posed Inverse Problems: a Note in Memory of Pierre Sabatier

Gaoming Chen, Fadil Santosa, William W. Symes

Professor Pierre Sabatier contributed much to the study of inverse problems in theory and practice. Two of these contributions were a focus on theory that actually supports practic…

A numerical investigation of Matched Source Waveform Inversion applied to acoustic transmission data

William W. Symes, Huiyi Chen, Susan E. Minkoff

Iterative inversion of seismic, ultrasonic, and other wave data by local gradient-based optimization of mean-square data prediction error (Full Waveform Inversion or FWI) can fail…

Adaptive waveform inversion for transmitted wave data

William W. Symes

Adaptive Waveform Inversion (AWI) applied to transient transmitted wave data can yield estimates of index of refraction (or wave velocity) similar to those obtained by travel time…

Efficient Computation of Extended Surface Sources

William W. Symes

Source extension is a reformulation of inverse problems in wave propagation, that at least in some cases leads to computationally tractable iterative solution methods. The core sub…

Solution of an Acoustic Transmission Inverse Problem by Extended Inversion

William W. Symes, Huiyi Chen, Susan E. Minkoff

Study of a simple single-trace transmission example shows how an extended source formulation of full-waveform inversion can produce an optimization problem without spurious local m…
