Abstract
Location and identification of subterranean infrastructure is crucial for managing
and maintaining urban infrastructure and utility, and locating subsurface hazards.
Low-frequency oscillating magnetic fields suffer less attenuation due to propagating
through media than ground penetrating radar. Here, electronically-geared, rotating neodymium magnets project oscillating magnetic fields which are manipulated
to provide object identification from rapid analysis of dynamic magnetometer data.
Ferromagnetic materials interact directly with the rotating magnetic field. Eddy currents, which induce a counter-propagating magnetic field, are generated in conductive,
non-ferromagnetic materials. Two applications are highlighted by preliminary experiments: discrimination between copper, aluminum and steel pipes, and improved
detection of buried explosive devices.
