Handheld UXO Sensor Improvements to Facilitate UXO/Clutter Discrimination. Volume 1

Abstract

This work was a collaborative effort between Duke University and SAIC (formerly AETC Incorporated). The final report consists of two volumes. This first volume gives a complete description of the overall effort as it evolved and culminated in a successful demonstration of IMU-based positioning of a handheld EM61 sensor for data collection to support target characterization of buried UXO. Volume 2 is a complete report of the supporting activities at Duke University. The goal of this project was to develop an inexpensive, robust way to accurately determine the trajectory of a handheld UXO sensor as it is swept about above a suspected buried UXO item. In principle, the sensor position and orientation can be tracked using an inertial measurement unit (IMU) that measures accelerations and angular rates along three orthogonal axes. Whether a compact, inexpensive, rugged IMU based on micro-electromechanical systems (MEMS) technology is sufficient to do the job was a main focus of this project. Another point of focus was the development of processing procedures that combine the trajectory with the sensor output stream to characterize the target for discrimination between UXO and clutter.
