METHOD FOR PHASE AND AMPLITUDE CORRECTION IN CONTROLLED SOURCE ELECTROMAGNETIC SURVEY DATA

摘要

The method for correcting the phase of measured electric signals or magnetic signals of field data from a controlled source electromagnetic survey (CSES) by comparing the measured field data corresponding to a selected frequency to the simulated data for various signal source receiver offsets (71) and correcting the phases of the actual data based on the phase difference for a selected range of small signal offsets (76) based on a go-electric model.
