Characterization and quantification of magnetic remanence in unexploded ordnance

Under the Range Rule (1997), the Department of Defense defines unexploded ordnance (UXO) as a piece of ordnance that has been deployed, but has not exploded. This study investigated a subset of UXO including artillery shells and mortars (projectiles), but excluding landmines. UXO contaminates approximately 15 million acres of land in the United States alone. The geophysical tools most frequentl...

Evaluating the Effects of Magnetic Susceptibility in Uxo Discrimination Problems

Past unexploded ordnance (UXO) clearance projects have demonstrated that the ability to detect UXO can be seriously hindered by the presence of magnetic rocks and soils. In particular, magnetic material affects the decay curve characteristics in electromagnetic surveys and this can adversely affect inversion calculations that try to estimate parameters of the UXO or answer the question of wheth...

Genetic Programming for Discrimination of Buried Unexploded Ordnance (UXO)

According to the Department of Defense, over 10 million acres of land in the US need to be cleared of buried unexploded ordnance (UXO). Worldwide, UXO injures thousands each year. Cleanup costs are prohibitively expensive due to the difficulties in discriminating buried UXO from other inert non-UXO objects. Government agencies are actively searching for improved sensor methodologies to detect a...

Improving UXO discrimination using magnetic quadrupole moments

Currently there are no UXO discrimination techniques based on total-field magnetic sensor data that rely on multipole expansion parameters of higher order than the dipole. In some cases, however, it can be advantages to describe a UXO target with both dipole and quadrupole parameters. In this paper, we examine the properties of the quadrupole moment and illustrate them using a synthetic example...
