Abstract
The effectiveness of automatic amplitude adjustment before Vibroseis® correlation (Coruh and Costain, 1983) to whiten seismic data leads to this paper which presents a general method based on automatic amplitude adjustment after stretching ordinary seismic data. The central feature of this method is the ability to separate spectral components of data in time and then to balance separated spectral components for whitening before data are compressed back. The method whitens data in a time‐variant fashion and is called stretched automatic amplitude adjustment or stretched automatic gain control (SAGC).
