Detection of Magnetic Anomaly UsingTotal Field Magnetometer

Abstract

Magnetic anomaly detection (MAD) is a passive method for detecting ferromagnetic objects to detect anomalies in the Earth's magnetic field, specific hidden targets. In this work, we aim at detecting a ferromagnetic moving target using a static referenced Total Field Magnetometer. We use the two magnetometers outputs to build a total magnetic field of the target. In most of the articles used Three-Axis Magnetometer but in this paper for the first time used One-Axis Magnetometer.This signal is subtract of two magnetometers outputs that we can use a signal integration to increase of SNR. Our analysis is supported by a computer simulation.The high detection probability and the simple implementation of the proposed method make it attractiv.
