Diffraction-based velocity estimates from optimum offset seismic data

A graphical method is characterized for estimating seismic velocity directly from diffraction patterns observed on common offset records. The nature of the resulting estimate is examined by illustrating the connection between the graphical approach and a related method used by practioners of ground penetrating radar. While the latter provides only a crude stacking velocity, the graphical technique yields the generalized rms velocity for stratified media. -from Authors
