Title: (FR) SOURCE SISMIQUE ET PROCEDE DE REDUCTION DE INTERMODULATION.
(EN) Seismic source and method for intermodulation mitigation
(DE) Seismische Quelle und Verfahren zur Intermodulationsabschwachung
Abstract:
(EN) A method for calculating intermodulation noise generated with one or more land seismic sources. The method includes receiving seismic data generated by actuating the one or more land seismic source with a first sweep and a second sweep; calculating with a computing device a first earth response corresponding to the first sweep; calculating with the computing device a second earth response corresponding to the second sweep; and calculating the intermodulation noise based on the first and second earth responses. The second sweep is a time reverse sweep of the first sweep.
