This paper discusses the design,construction,and simulation of a beat frequency oscillator metal detector. Over the years, it has become an important issue to limit, the entry of people into certain places with weapons or instruments of harm and this paper is a design of an effective means of detecting dangerous weapons made of metal in order to reduce crime rate in the society. It uses the principle of electromagnetic induction and adopts a digital beat frequency technique. The…

System for interpreting the characteristics of metal objects based on signal acquired from a magnetic loop antenna

This article describes a laboratory experimental system used for the study of detection and feature interpretation of an object containing metal or material with magnetic properties held by people in

Metal Detector Based on Lorentz Dispersion

Lorentz Dispersion regime is a narrowband spectral region characterized by a sharp resonance dip and an anomalous phase response. Due to its high dispersive nature, the Lorentz resonance is very

Improved mechanisms of active magnetic sensing for subterranean target discrimination

This paper describes an active magnetic sensing system that locates and distinguishes buried ferromagnetic and non ferromagnetic objects. The operating principle is that primary active magnetic

An attempt is made to theoretically analyze the properties, such as size, conductivity, and permeability of the metal objects from the output, i.e., amplitude and phase of theMetal detector.

Discrimination experiments with the U.S. Army's standard metal detector

Discrimination experiments with the U.S. Army's standard hand‐held metal detector (AN/PSS‐12) are described. An appendix describes the functioning of the device as a metal detector, and the body of

Intelligent Metal Detector

Humanitarian demining is a matter of high interest, but metal contamination and magnetic soils reduce the sensitivity of metal detectors. The soil contamination also increases the numbers of false

Electromagnetics with Applications

Adapted to tie in with the university curriculum and suitable for a one term course, this book covers numerical techniques and accessible computer programs, giving students the chance to gain direct
