Recorded seismic reflection waveforms contain information as to the small-scale variations
of impedance and the large-scale variations of velocity. This information can be retrieved by …

Full-waveform inversion of seismic reflection data is highly nonlinear because of the
irregular form of the function measuring the misfit between the observed and the synthetic …

This paper proposes a reflectivity constraint for velocity estimation to optimally solve the
inverse problem for active seismic imaging. This constraint is based on the velocity model …

Full waveform inversion applied to surface seismic data containing only reflection data
generally gives an impedance map, the background velocity being assumed known. The …

We study the inverse problem of determining the impedance of a one-dimensional medium
from reflection data which are band-limited and uncalibrated. The problem arises in seismic …

This paper examines the problem of recovering the acoustic impedance from band-limited
normal incidence reflection seismograms. Recognizing the inherent nonuniqueness in the …

The loss of low-frequency information in reflection seismograms causes serious difficulties
when attempting to generate a full-band impedance profile. Information about the low …

This paper examines the problem of recovering the acoustic impedance from a band-limited
normal incidence reflection seismogram. The convolutional model for the seismogram is …

Waveform inversion aims at a quantitative estimation of the subsurface model. Such a
quantitative estimation is a nonlinear problem: the relation between elastic parameters and …

In seismic imaging, one tries to infer the medium properties of the subsurface from seismic
reflection data. These data are the result of an active source experiment, where an explosive …
