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.

An improved neural network method for aeromagnetic compensation
Measurement Science and Technology, 2021Abstract Aeromagnetic compensation plays an important role in aeromagnetic data processing and can eliminate the magnetic interference generated by aircraft. Currently, aeromagnetic compensation algorithms are mostly based on linear regression equations, but linear regression has insufficient fitting function capabilities compared to ...

Aeromagnetic Gradiometry And Compensation
5th SAGA Biennial Conference and Exhibition, 1997Although the concepts of aeromagnetic gradiometry are not new, it is only in the past several years, with a handful of gradient-equipped aircraft becoming operational, that the benefits are being realized. The main applications to date are the following: • In a total field survey, a lateral gradiometer provides additional information about the field ...

Performance measures in aeromagnetic compensation
The Leading Edge, 2011Aeromagnetic compensation is essential for the generation of highly accurate data in airborne geophysical surveys. Its objective is the removal of magnetic interference (or noise) in the signals, measured by magnetometer sensors, which is caused by the maneuvering of an aircraft flying within the Earth's magnetic field.

Aeromagnetic compensation using neural networks
Neural Computing & Applications, 1993Airborne magnetic surveys in geophysical exploration can be subject to interference effects from the aircraft. Principal sources are the permanent magnetism of various parts of the aircraft, induction effects created by the earth's magnetic field and eddy-current fields produced by the aircraft's manoeuvres.

Adaptive techniques and other recent developments in aeromagnetic compensation
First Break, 2017Aeromagnetic compensation, an integral part of most airborne geophysical exploration programmes, has received considerable attention throughout the last few decades. Advanced compensation systems, rooted in the original model which accounts for aircraft interference from permanent, induced, and eddy-current sources, have led to significant advances ...
