  Abstract

A ferromagnetic target detection system detects a magnetic anomaly generated from the ferromagnetic target in the geomagnetic field. The three-axis magnetic vector sensor is orthogonal and considered as a technique for extending the detection distance. However, in the conventional ferromagnetic target detection system, the target is detected using the magnitude value calculated from the three-axis signal only, and the sensitivity of the three-axis signal which has been changed by the ferromagnetic target can not be directly reflected. In addition, when the axis of the magnetic vector sensor was physically rotated due to environmental influences, the performance of the target detection system using the 3-axis signal is deteriorated because the magnitude and pattern of the 3-axis signal are changed by rotated angles. In this paper, we propose a continuous angle alignment scheme to extend the detection distance for the ferromagnetic target and to reduce the false alarm rate. Performance evaluation results show that the proposed scheme can extend the detection distance compared to the conventional scheme.
