A method of seismic surveying using one or more vibrational seismic energy sources activated by sweep signals. The highest order harmonic that has sufficient strength to cause significant harmonic distortion of a sweep segment is determined. A number of sweep segments in excess of the number of sources is selected. Initial phase angles are selected for each sweep segment of each seismic energy source so that substantially all harmonics up to and including the highest order harmonic are suppressed. Using cascaded sweeps, seismic data are acquired and processed to substantially attenuate harmonics upto the selected order.

L'invention porte sur un procédé d'étude sismique utilisant au moins une source d'énergie sismique provoquant des vibrations, activée par des signaux de balayage. Ledit procédé consiste à : déterminer l'harmonique d'ordre le plus élevé possédant une intensité suffisante pour provoquer la distorsion harmonique significative d'un segment de balayage ; à sélectionner plusieurs segments de balayage dépassant le nombre de sources ; à choisir des angles de phase initiaux pour chaque segment de balayage de chacune des sources d'énergie sismique de manière que toutes les harmoniques, de l'ordre de ou incluant l'harmonique d'ordre le plus élevé, soient sensiblement toutes supprimées. L'utilisation de balayages en cascade permet d'obtenir et de traiter des données sismiques avec sensiblement une atténuation des harmoniques à hauteur de l'ordre choisi.
