Frequency Domain Electromagnetic UXO Detector

3 loop system Poster Presentation Detector System In the Field

Overview

Built a Frequency Domain Electromagnetic Survey device for UXO detection using Geophysical Inversion techniques as a part of my Engineering Physics Capstone project. The detector used a custom coil system to magnetically excite the ground and embedded conductive objects and measured the response to determine the location and size of buried objects and the ground parameters. Work was done in collaboration with UBC Department of Earth, Ocean, and Atmospheric Sciences.
