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...

The paper presents an algorithm for automatic detection of UXO anomalies in total-field magnetic data based on the concept of structural index (SI) of a magnetic anomaly. The magnetic field produced by a dipole-like source, such as a UXO, varies with inverse distance cubed and therefore has an SI of 3. Identifying magnetic anomalies having structural indices of 3 enables direct detection of pot...

We have applied an automatic interpretation method of potential data called AN-EUL in unexploded ordnance (UXO) prospective which is indeed a combination of the analytic signal and the Euler deconvolution approaches. The method can be applied for both magnetic and gravity data as well for gradient surveys based upon the concept of the structural index (SI) of a potential anomaly which is relate...

We will report on first tests of a commercial “imaging metal detector” aimed at trying to assess its potentialities and understand in a broader sense if such systems, possibly in a modified form, could be useful to tackle some aspects of the UXO/mine detection problem. The latter include the detection of shallowly buried Unexploded Ordnance (UXO) (e.g. in Laos) or non minimum-metal mines such a...

In this chapter, we outline the statistical procedures that can be employed for the detection of unexploded ordnance (UXO). Phenomenological modeling is first developed to relate the collected data to a sensor’s feature parameters, which in turn allow for physics-based signal processing. Starting with the Bayesian framework, we introduce minimax and robust detection that do not require prior pr...

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...

An ultra-wideband (UWB) synthetic aperture radar (SAR) system is investigated for the detection of former bombing ranges, littered by unexploded ordnance (UXO). The objective is detection of a high enough percentage of surface and shallow-buried UXO, with a low enough false-alarm rate, such that a former range can be detected. The physics of UWB SAR scattering is exploited in the context of a h...
