Common reflection area stack(CRA)is a method suppressing random noise.The method can be applied to improve signal/noise ratio of seismic data throughsame phase stackingfor reflection seismic record of CDPs (2D)or common reflection area(3D)on stacking profile or migration profile,adding seismic trace for stacking.The basic keeping amplitude is approved by modeling and seismic data processing effect.CRA is better than other methods for suppressing random noise on keeping amplitude.
