Title: (EN) METHOD FOR WAVEFIELD SEPARATION FOR DUAL-SENSOR DATA USING KIRCHHOFF-TYPE DATUMING AND MIGRATION
Abstract:
(EN) A first weighted integral operator is applied to dual-sensor data to extrapolate the dual-sensor data to a first position above an acquisition surface, generating extrapolated data. A second weighted integral operator is applied to the extrapolated data to extrapolate the extrapolated data to a second position, generating wavefield separated data. One of the integral operators is applied to a scaled combination of the dual sensor data.
