Real-time localization of a magnetic object with total field data

A wide interest arises in magnetic anomaly detection due to its application in many areas. In the inverse problems of magnetic anomaly detection, localization technique of magnetic objects is always focused on. In some cases, there is an increasing need for automatic magnetic detection technique in real time. Based on Eulerpsilas homogeneity equation, a real-time localization model was founded with total magnetic field data. The basic principle is detailed in this paper. By the numerical simulations of magnetic source localization, it is shown that the technique has high accuracy and it is a real-time method in automatic magnetic anomaly detection.
