Application of Phase-Based Edge Detectors to Magnetic Data for Explosive Ordnance Detection
Geophysical sensing methods such as magnetics, electromagnetics and ground penetrating radar are the essential methods for the detection of unexploded ordnances (UXO) in the subsurface. Apart from a precise localization of buried ammunition remnants, a reliable discrimination of anomaly signatures caused by UXO and Non-UXO bodies is one of the currently most challenging tasks in the ﬁeld of explosive ordnance clearance. Therefore, we exploit diﬀerent phase-based edge detectors to evaluate their applicability for improving the detection performance and especially for distinguishing buried objects by the anomaly signature they cause. In the present poster, we apply our new approach on synthetic magnetic data for spherical and elliptical object geometries. Furthermore, we compare the synthetic cases to real magnetic survey data collected from a test site at SENSYS GmbH in Bad Saarow.
