Evaluating the Effects of Magnetic Susceptibility in Uxo Discrimination Problems
نویسندگان
چکیده
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 whether the item is UXO or scrap. Our research is in two parts. Firstly, we carry out numerical 1D forward modelling to evaluate the distortions of signals due to laterally uniform magnetic material. In the second part of the talk we examine how the distortions in the signal affect our inversion algorithms used for UXO discrimination.

Effects of Magnetic Soils on Magnetometry in Uxo Discrimination Problems
Magnetometry has emerged as an effective tool for UXO discrimination. The current approach is based upon the magnetic dipole moment recovered from the inversion of surface total-field magnetic anomalies. However, the reliability of inversion will be strongly influenced by the noise in the data such as that produced by magnetic soils in the background geology. We examine this problem to understa...
متن کاملEnhancing magnetic signals in unexploded ordnances (UXO) detection based on edge-preserved stable downward continuation method
This paper describes an efficient edge-preserved regularization algorithm for downward continuation of magnetic data in detection of unexploded ordnance (UXO). The magnetic anomalies arising from multi-source UXO can overlap at a height over the ground surface, while causative sources may not be readily separated due to low level of signal-to-noise ratio of the observed data. To effectively the...
متن کاملClassification of Magnetic Susceptibility Anomalies and Their Relevance to UXO Detection
The attention given the natural geologic background of a site and its influence on geophysical sensors has grown considerably over the past several years, primarily because of the governmentsupported unexploded ordnance (UXO) technology demonstrations and government mandated UXO cleanup activities. Explosive and ordnance detection (EOD) teams have encountered difficulties at sites thought to be...
متن کاملImproving 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...
متن کاملA Finite Element Method for the Electromagnetic Characterization of Quasi-Magnetostatic Problems Found in UXO Detection and Discrimination
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...
