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 ...

Uncertainty Estimation in the Neural Model for Aeromagnetic Compensation
IEEE Geoscience and Remote Sensing Letters, 2018Measuring the performance of an aeromagnetic compensation system is usually difficult. The standard deviation of the signal has been used as an index in the industry. While the standard deviation is drawn from frequency statistics, it cannot represent the performance on a single sampling point.

A dual estimate method for aeromagnetic compensation
Measurement Science and Technology, 2017Abstract Scalar aeromagnetic surveys have played a vital role in prospecting. However, before analysis of the surveys’ aeromagnetic data is possible, the aircraft’s magnetic interference should be removed. The extensively adopted linear model for aeromagnetic compensation is computationally efficient but faces an underfitting problem.

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 ...

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.

Modeling and reduction of the gradient effect of a magnetic sensor for an aeromagnetic compensator
Review of Scientific Instruments, 2021The traditional aeromagnetic compensation model does not consider the negative effects of the gradient of the geomagnetic background field. Especially in emergency aeromagnetic surveys, this gradient effect is obvious and can reduce the performance of magnetic compensation.

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.

An Automatic Method to Estimate the Calibration Quality of the Aeromagnetic Compensation
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Aeromagnetic compensation is an effective technique to reduce magnetic interference of the aircraft during an aero-magnetic survey. As an important indicator to evaluate the compensation effect, the figure of merit (FOM) is widely applied. However, calculating FOM needs to label the maneuvers manually.

A Simulation Method of Generating the Output of Magnetometer for Aeromagnetic Compensation
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019Most data used to develop the magnetic interference compensation algorithms are derived from the actual measurement of aerial magnetometer. However, it takes a long time and high cost to get the actual data, which will increase the time and difficulty for algorithms development. In practice, simulation magnetic data can be generated for the development
