摘要

Method for estimating a model of seismic velocity in a subsurface region from seismic data (31) recorded on 3-component instruments. The method measures the apparent incidence angle (32) of a seismic wave observed at a surface as a function of wave frequency. This apparent angle is converted to an effective velocity as a function of frequency (33), which is then inverted (34) to obtain a subsurface velocity model.
