A Finite Element Method (FEM) is presented to solve for the scattered magnetic vector potential from arbitrarily polarized targets typical of those encountered in Unexploded Ordnance (UXO) detection. Most previously developed numerical methods only solved problems in which axial symmetry could be exploited. This, of course, severely limits the capabilities and utility of such methods. The metho...

Objective: The objective of the current research is to work towards resolving issues that affect sonar detection and classification/identification (C/ID) of underwater UXO using sonar. Background: Based on extensive assessments of other sensor technologies carried out at NSWC PCD for underwater Navy applications, sonar is expected to play an indispensible role in underwater UXO remediation. Aco...

Airborne magnetic systems for mapping unexploded ordnance (UXO) and other shallow metals have been developed at Oak Ridge National Laboratory (ORNL) over the past five years .We have recently completed testing of a time-domain electromagnetic (EM) system to supplement the magnetic system for UXO investigations. The test was conducted at the Badlands Bombing Range (BBR) in South Dakota in Septem...

Emerging applications in Defense and Security require sensors with state-of-the-art sensitivity and capabilities. Among these sensors, the imaging spectrometer is an instrument yielding a large amount of rich information about the measured scene. This powerful spectrometric tool is becoming more common in civil applications such as search and rescue, geological surveys, pollution monitoring, fo...

The integrated editor UXO is the result of ongoing research and development of the text-technology group at Bielefeld. Being a full featured XML-based editing system, it also allows to combine the structured annotated data with information imported from relational databases by integrating a JDBC interface. The mapping processes between different levels of annotation can be programmed either by ...

Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including s...

Most unexploded ordinance (UXO) are heterogeneous objects containing parts of different metals, e.g., head, body, tail and fins, copper banding, etc. Recently, low frequency electromagnetic induction (EMI) sensing, based on the EM diffusion phenomena, has shown considerable progress for the detection and discrimination of UXO. EMI responses are sensitive to the type of metal (conductivity and p...
