Abstract

Aiming at the magnetic research of unexploded ordnance with various attitudes and shapes, a magnetic measurement and analysis method of unexploded ordnance is proposed. In this paper, the model of unexploded ordnance magnetic field source is established, and the equipment for multi detector parallel acquisition of unexploded ordnance magnetic field data is designed. After obtaining the information of unexploded ordnance magnetic field, the data repair and inversion calculation are carried out, so as to obtain the magnetic characteristics of unexploded ordnance. The experimental results show that this method can not only quickly and effectively obtain the magnetic field information of the detection surface of unexploded ordnance, but also retrieve its magnetic moment and buried depth, and the error is less than 20%. This research has important reference value for the magnetic analysis and detection of unexploded ordnance.
