Paper Abstract

Many different coil head configurations are used in electromagnetic induction (EMI) systems for sensing buried targets. The design of these types of coils is not well described in current literature, and it is difficult to compare the performance of different coil head designs to one another. Comparing two particular implementations is not particularly challenging, but fairly comparing general coil head designs is nontrivial. This work details normalized target sensitivity and soil sensitivity metrics that account for differences such as overall coil size, length, and wire diameter and for variations in sensitivity patterns. The metrics are used to optimize double-D, dipole/quadrupole, and concentric coil head designs, which are then analayzed and compared to one another.
