Next Generation Geophysical Assessment System
Autor: Ben Barrowes, Gray D. Thurston, John Schmalzel
Publikováno v: 2021 IEEE Sensors Applications Symposium (SAS).
Electromagnetic induction has been utilized in the past by the United States Army Corps of Engineers as a method of detecting unexploded ordinance. Recently an EMI instrument was built that extended the traditional EMI frequency range from 100 kHz to

UAS NOISE IN STANDOFF EMI MEASUREMENTS
Autor: Kevin O'Neill, Danney R. Glaser, Mikheil Prishvin, B. Quinn, Fridon Shubitidze, Ben Barrowes
Publikováno v: Symposium on the Application of Geophysics to Engineering and Environmental Problems 2019.
We present data showing the impact of unmanned aerial systems (UAS) propeller motors electrical noise on the acquisition of electromagnetic induction (EMI) signals. Multiple motor speeds and standoff distances are evaluated. Results indicate an optim

UXO classification procedures applied to advanced EMI sensors and models
Autor: Irma Shamatava, John B. Sigman, Fridon Shubitidze, Ben Barrowes, Kevin O'Neill
Unexploded Ordnances (UXO) classification procedure consists of the following: background subtractions, data inversions and targets feature parameters estimations, and separating UXO from non-hazardous anomalies. First, each dataset is normalized by

Detection of conductivity voids and landmines using high frequency electromagnetic induction
Autor: Hollis J. Bennett, John B. Sigman, Fridon Shubitidze, Janet E. Simms, Ben Barrowes, Donald E. Yule, Kevin O'Neill
Publikováno v: 2016 XXIst International Seminar/Workshop on Direct and Inverse Problems of Electromagnetic and Acoustic Wave Theory (DIPED).
Electromagnetic induction (EMI) instruments have been traditionally used to detect high electric conductivity discrete targets such as metal unexploded ordnance (UXO). The frequencies used for this EMI regime have typically been less than 100 kHz. To

A New Physics-Based Approach for Estimating a Buried Object's Location, Orientation and Magnetic Polarization from EMI Data
Autor: Irma Shamatava, David Karkashadze, Kevin O'Neill, Ben Barrowes, Fridon Shubitidze
Publikováno v: Journal of Environmental & Engineering Geophysics. 13:115-130
A new physics-based expression is presented for determining a buried object’s location, orientation and magnetic polarizibility. The approach assumes the target exhibits a dipolar response and requires only three global values: a magnetic field vec
