Removing the earth's main field in processing of airborne magnetic data

LUO Yao;LUO Feng;WANG Ming;HE Hui;WANG Lin-fei;China Aero Geophysical Survey and Remote Sensing Center for Land and Resources;  
We can get magnetic anomalies by removing the normal magnetic field background of the earth,the normal magnetic field correction is a crucial step in airborne magnetic data processing.Based on the principle and practice,we discussed how to calculate the international geomagnetic reference field(IGRF)and how to correct the IGRF in airborne magnetic data processing.The discussions for the misunderstanding in the criterion for aeromagnetic survey should also be noted in the ground magnetic exploration.
