Determination of buried magnetic material’s geometric dimensions

Abstract

It is important to find buried magnetic material’s geometric features that are parallel to the soil surface in order to determine anti-tank and anti-personnel mine compatible to standards. So that it is possible to decrease the number of false alarms by separating the samples that have got non-standard geometries. For this purpose, in this study the anomalies occurred at horizontal component of the earth’s magnetic field by buried samples are determined with magnetic sensor. In the study, KMZ51 AMR is used as the magnetic sensor. The position-controlled movement of the sensor along x-y axis is provided with 2D scanning system. Trigger values of sensor output are evaluated with respect to the scanning field. The experiments are redone for the samples at different geometries and variables are defined for geometric analysis. The experimental conclusions obtained from this paper will be discussed in detail.
