The early detection of terrorist threat objects, such as guns and knives, through improved metal detection, has the potential to reduce the number of attacks and improve public safety and security. To achieve this, there is considerable potential to use the fields applied and measured by a metal detector to discriminate between different shapes and different metals since, hidden within the field perturbation, is object characterization information. The magnetic polarizability tensor (MPT… 


Identification of metallic objects using spectral magnetic polarizability tensor signatures: Object characterisation and invariants
This article describes the additional characterisation information that measurements of the induced voltage over a range of frequencies offer compared with measurements at a single frequency, and presents a series of alternative rotational invariants for the purpose of classifying hidden objects using MPT spectral signatures.
KNN classification of metallic targets using the magnetic polarizability tensor
The extent to which a K-nearest-neighbour classifier can distinguish various kinds of metallic objects, such as knives, shoe shanks, belts and containers is studied.
Measurement of GMPT Coefficients for Improved Object Characterisation in Metal Detection
Magnetic polarizability tensors (MPTs) have become popular for characterising conducting permeable objects and assisting with the identification of hidden objects in metal detection for applications
The spectral properties of the magnetic polarizability tensor for metallic object characterisation
The measurement of time‐harmonic perturbed field data, at a range of frequencies, is beneficial for practical metal detection, where the goal is to locate and identify hidden targets. In particular,
Characterizing the shape and material properties of hidden targets from magnetic induction data
The purpose of this paper is to clear up a major mystery in metal detection and confirm that the engineering prediction of HT .M.HM, for the sensitivity of measurements of the perturbed magnetic
Threat Identification in Humanitarian Demining Using Machine Learning and Spectroscopic Metal Detection
A new algorithm for threat identification for MIS sensors, based on a fully-connected artificial neural network (ANN), is proposed and compared against a classifier based on Support Vector Machines (SVM), demonstrating that MIS is a potentially viable option for the reduction of false alarms in humanitarian demining.
Magnetic Polarizability Tensor Spectroscopy for Low Metal Anti-Personnel Mine Surrogates
The magnetic dipole polarizability tensor is an object-specific property possessing information about the size, shape, and material. This information could be used by electromagnetic induction
Determining the Electromagnetic Polarizability Tensors of Metal Objects During In-Line Scanning
The general approach to determining the tensor during in-line scanning is introduced and it is suggested that tensor inversion is possible for the 2-D raster scan, but not for a single line scan.
Characterisation of multiple conducting permeable objects in metal detection by polarizability tensors
Realistic applications in metal detection involve multiple inhomogeneous‐conducting permeable objects, and the aim of this paper is to characterise such objects by polarizability tensors. We show
Measuring the Magnetic Polarizability Tensor Using an Axial Multi-Coil Geometry
The Magnetic Polarizability Tensor (MPT) is a representative property of an electrically conducting or magnetic object that includes information about the object’s characteristics such as, shape,
