Abstract

A surficial distribution of scrap metal can have a very similar EM response to a buried UXO when measured only with a vertical-component sensor. Discrimination on the basis of time constants or quality of an inversion fit appear to be weak. However the sensor horizontal component transverse to a profile is highly sensitive to the presence of scrap. We demonstrate that the ratio of power in the spatial derivative of the y-component profile, to the power in the unfiltered profile, provides a strong discriminator between signatures of scrap and intact UXOs.
