Abstract
Systems and methods to detect ferromagnetic objects, particularly submerged, non-naturally occurring ferromagnetic objects, account for contributions to the magnetic field arising from topography, such as magnetic refraction at bathymetric slopes. Removing this topography component of noise from detected total magnetic field enhances detection capability of, for example, naval surveillance systems.
