Embedding target discrimination capabilities into commercial handheld metal detectors for humanitarian demining

In this paper, we analyze the technical framework for embedding target discrimination capabilities into commercial handheld metal detectors (HMD) for use in humanitarian demining. We introduce the target discrimination concept based on the application of directional magnetic polarizabilities, determined from HMD response and positional data of its search head. We identify five key technical factors that need to be addressed for the purpose of target discrimination based on the proposed concept, namely (i) the analysis of MD search head in terms of its directional sensitivities ; (ii) analysis of MD signal processing features, (iii) search head tracking system ; (iv) novel human-machine interface (HMI) ; and (v) operating procedures needed for supporting these new HMD functionalities. We analyzed the existing technical approaches and proposed some new changes that could bring the whole concept a step closer to realization.
