Hand-Held EMI Sensor Combined with Inertial Positioning for Cued UXO Discrimination - APG Standardized UXO Test Site
Abstract
The objective of this work was to combine a Small Area Inertial Measurement Tracking System (SAINT) with an advanced hand-held, time-domain electromagnetic sensor (TEM-HH) and document classification performance at the Standardized UXO Test Site at Aberdeen Proving Ground, Maryland. The TEM-HH has a single, circular, 35-cm diameter transmit coil and an inner, circular, 25-cm diameter receive coil. The SAINT integrates an inertial measurement unit and a digital magnetic compass. The two data streams were collected separately and merged during post processing. Cued data collections occurred over APG's Calibration Lanes and the Blind Grid Area at an average rate of 27 per hour. Target classification was based on a comparison of principal axis polarizabilities from a dipole fit for each anomaly to a known signature library. Our classification objectives were met; 97% of the UXO was identified as UXO (the other 3% were not detected) while rejecting 77% of the clutter.
