Sažetak
Search coils of handheld metal detectors (HMD) employed for detection of buried landmines typically feature planar designs, normally based on single transmitter and one or more receiver coils. Such designs are usually optimized with respect to detector sensitivity to small metallic targets in a single (e.g. vertical) direction only. Capturing a target's induced responses corresponding to all possible directions of transmitted/received magnetic fields opens up a possibility of reconstructing the target's magnetic polarizability tensor. The elements of this tensor are closely related to target's geometrical and material properties. In effect, an HMD could be considered as a potential target characterization tool, which is important for improving target discrimination capabilities of current HMD technology. In this paper, we analyze directional sensitivities of three different search coil designs, typically found in the humanitarian demining industry, and asses their applicability for target characterization.
