Samenvatting

We have analysed an extensive amount of metal detector raw data using a commercially available differential CW system, the Förster Minex 2FD. Qualitative aspects of the phase response behaviour (signal trajectories in the complex plane) have been detailed in a companion paper [1], showing that a “qualitative” target classification is possible, at least for situations with high Signal to Noise (S/N) ratios. In this article we extend the previous results providing a quantitative analysis.
We define a number of features and propose ways to calculate them in practice from the experimental data sets available. The resulting feature distributions are then analysed and object classification opportunities discussed. Conclusions are then drawn on the possibility of a coarse object classification based on the object size and permeability, and on the possibility of discriminating large objects and mines.
