Improvement of Magnetic Exploration Device Using Differential Magnetic Sensor for Detecting Unexploded Ordnance

Abstract

A new method to detect unexploded ordnance is proposed in this study. Magnetic exploration system using a plurality of differential magnetic sensor with different distance is used. By comparing the plurality of differential outputs simultaneously, we can reduce the influence of the magnetic field from outside of the search-area. Unexploded ordnance will be detected correctly in spite of the place where conventional method cannot detect.
