Matched Filter Processor for Detection and Discrimination of Unexploded Ordnance: OASIS Montaj Integration
Abstract
Identifying magnetic signatures that result from unexploded ordnance (UXO) is complicated by the dipolar nature of the signatures themselves and the presence of non-target-generated magnetic fluctuations. Fluctuations in the magnetic field that result from naturally occurring geologic materials, for example, often obscure the signatures from UXO. The presence of metallic debris or shrapnel can also degrade, mask, or complicate analysis. To improve and automate the analysis of magnetic data, a matched filter autoprocessor was investigated in 2001 under ESTCP funding. The matched filter algorithm, which was originally codified in the Interactive Data Language (IDL; Research Systems, Inc.), implements optimal linear filtering in a threshold-based UXO detection scheme. The objective of this work was to recode the algorithm such that it seamlessly integrates with OASIS Montaj. OASIS Montaj, developed and marketed commercially by Geosoft, Inc., includes a very large capacity database, a graphical user interface, and a plethora of geophysical processing and mapping routines.
