29 May 2014 Multi-channel transmit/receive metal detector coil design for vehicular applications
Author Affiliations +
Metal detector coil design has been matured to great extent over the years. However, vehicle mounted or remotely operated metal detectors require different specifications and these specifications dictate multiple transmit and receive coils operating in various settings. Unlike handheld operation, detector is more susceptible to metallic body of the vehicle. Moreover, ground calibration is also different than handheld devices. Coil geometries and intercoupling between them play a significant role in system design and performance. In this study, we study different coil geometries for vehicular applications. Starting from well-known coil geometries, we placed coils on dry, wet and ferrous soil to understand the interaction mechanism. Simulation studies are performed in frequency domain but the results are all applicable to time domain pulse based detector systems.
