Aeromagnetic Compensation With Suppressing Heading Error of the Scalar Atomic Magnetometer
IEEE Geoscience and Remote Sensing Letters, 2020Scalar atomic magnetometer (SAM) with high sensitivity is designed to measure the total magnetic field and has been widely applied in aeromagnetic surveys. However, the measured total magnetic field of SAM is influenced by the magnetic disturbances due to the permanent, induced and eddy-current fields of the aircraft and heading errors of SAM.

An Aeromagnetic Compensation Coefficient-Estimating Method Robust to Geomagnetic Gradient
IEEE Geoscience and Remote Sensing Letters, 2016Most existing methods used in aeromagnetic compensation assume a constant geomagnetic field. These methods do not take into consideration the geomagnetic gradient, which can reduce the accuracy of the estimated coefficients of the Tolles–Lawson model.

A simplified aeromagnetic compensation model for low magnetism UAV platform
2011 IEEE International Geoscience and Remote Sensing Symposium, 2011Magnetic interference generated by the air-borne platform is one of the most common system noises in aero-magnetic survey. The noise can be divided into 3 parts as the permanent, the induced and the eddy-current fields. A new air-borne platform called the Unmanned Aerial Vehicle (UAV) can be designed and manufactured with low magnetic interference ...

An Adaptive Filter for Aeromagnetic Compensation Based on Wavelet Multiresolution Analysis
IEEE Geoscience and Remote Sensing Letters, 2016In aeromagnetic compensation, the multicolinearity of the Tolles–Lawson model is one of the main factors limiting the performance of the coefficient-estimating methods. Aside from the intrinsic characteristic of the Tolles–Lawson model, data filtering as a preprocessing step in estimating the coefficients has a significant impact on the ...
