Dipole Discrimination Techniques Applied to Live Sites; MetalMapper Survey, Waikoloa HI

Abstract

This Demonstration Report describes processing of cued MetalMapper collected as part of an ESTCP demonstration conducted at the former Waikoloa Maneuver Area, Hawaii. A spatially-variable magnetic soil response was observed at this site, and separation of soil and target response during inversion was required to obtain useful polarizabilities for classification. The research team modelled soil response using a two-object inversion approach: one dipole source was fixed at 0.9 m depth below the ground and fit a soil response characterized by a log-linear time decay. The second source fit the dipolar response of any metallic target present in the cued sounding.
