Disclosed are a process and a system for improving seismic returns and other signals representative of non-time varying series which have been degraded by interaction with unknown wavelets. Use is made of a sequence of two-term operators, each derived from the most recent version of the signal and each applied thereto to obtain the next version. The operators are selected such that their application tends to increase the entropy of the signal, and to remove the effects of the unknown wavelets and change the observed signal in a manner which tends to reveal the signal of interest. |
