Metal detectors are unquestionably the workhorses of humanitarian demining. Although hybrid dual-sensor systems incorporating a ground penetrating radar (GPR) have recently been introduced and are gaining acceptance, a standard electromagnetic induction (EMI) sensor remains the primary mode of detection. Despite ongoing evolution and refinement of metal detector technology, however, the practical performance of both continuous wave (FDEM) and pulse induction (TDEM) systems continues to be restricted by so-called soil noise ...
