Unfortunately, gain corrections to restore signal strength at later times boost random noise in the process. Fortunately, CMP stack su

  • ...the synthetic traces were blended with a band-limited random noise, whose strength varied spatially. (The noise level was set to zero at both ends of the prof ...or data with a narrow bandwidth or high noise level, crosscorrelation can yield a multiple number of peaks and cause uncertainty in the estimated time shif

It is the substratum region where 3-D prestack depth [[migration]] would yield an improved image. The differences in amplitude characteristics and the ban
