(a) Decomposed synthetic at 6° incidence for layered medium model by SPWVD. (b) The balanced results of the decomposed synthetic. The effects of seismic wavelet at different frequency are eliminated by spectrum balance technique. The remaining energy differences with various frequencies at 0.2 s are caused by seismic dispersion.
