Scientific paper

A new approach is proposed whereby the stacking velocity and the zero-offset time of seismic wave propagation can be estimated simultaneously. The approach includes the following three major steps: preprocessing of the seismic data, estimating delays using a shift-invariant structure, and estimating stacking velocity and zero-offset time simultaneously from delay estimates. The effectiveness of the approach is demonstrated by computer simulations. The new approach has a higher resolution and is more computationally efficient than the traditional semblance approach.
