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

摘要

METHOD FT)R PHASE AND AMPLITUDE CORRECTION IN CONTROLLED SCURCE ELECTROMAGNETIC SURVEY DATA METHOD FOR CORRECTING THE PHASE OF MEASURED ELECTRIC OR MAGNETIC FIELD DATA FROM A CONTROLLED-SOURCE ELECTROMAGNETIC SURVEY BY COMPARING MCASUR6D DATA CORRESPONDING TO A SELECTED FREQUENCY TO SIMULATED DATA FOR VARIOUS SOURCE-RECEIVER OFFSETS, AND CORRECTING THE PHASES OF THE ACTUAL DATA BASED ON THE PHASE DIFFERENCE FOR A 5 SELECTED RANGE OF SMALL OFFSETS. AMPLITUDE ERRORS CAN BE SIMILARLY CORRECTED. 7(X)
