Abstract
Method for the processing of recordings of signals resulting from a seismic exploration of a medium. It consists, after grouping recordings in pairs and crosscorrelation of the recordings of each pair, in grouping the elementary crosscorrelation functions thus obtained in at least one family in which the measuring spaces are included in a same predetermined reference space, in transforming the time variables of the said functions in order to bring the measuring space dimension to that of the reference, then in adding the transformed functions. Application in particular to acoustic logging seismic reflection or refraction.
