ABSTRACT:
A process for non-linear matching of time analog signals, particularly seismic signals, that have generally similar response characteristics but different time bases is disclosed. The process models the signals to be matched as a stretched version of each signal with additive noise, and a match curve is estimated adhering to a global criterion of maximization of the likelihood function. The global criterion is further optimized in accordance with the principle of path optimality and other a priori information may also be considered. The match curve may then be used to identify such as correlated signal events, conparison of signal sections, and numerous seismic data processing functions using multidata or multisensor time analog data input.
