Polarity preserving decon in ``N log N'' time

Prevalence of Ricker wavelet

The conflict is most directly seen and addressed in the specific case of the Ricker wavelet. It is generally seen on the water bottom and on any strong reflector such as the top of salt and often the bottom of salt. The Ricker wavelet obscures recognition of multiple reflections by their polarity alternations. (For example, look ahead to the left side of Figure 2.)
