Metal target detection method using metal detector with synchronous demodulation
A recently granted patent (Publication Number: US11899156B2) outlines a method for detecting metal targets in soil using a metal detector. The method involves generating a transmit magnetic field, receiving first and second receive magnetic fields, and producing an indicator output signal based on these signals and synchronous demodulation functions. The parameters defining the transfer functions for the receive signals are carefully selected to reduce or null detected signals caused by soil eddy currents. The method also includes linearly combining the first and second receive signals and applying different gains to them to further reduce signals due to conducting soil components.
Additionally, the patent describes variations in the method, such as overlapping the transmit and receive windings, using different coil configurations like double D or concentric coils, and applying specific gain factors to the receive signals. The method aims to improve the accuracy of metal detection in soil, particularly in areas with salt content. Furthermore, the patent includes a provision for the method to be implemented through a non-transitory computer-readable medium containing the necessary code for execution by a processor of the metal detector. Overall, the patented method offers a comprehensive approach to enhancing metal detection capabilities in various soil conditions, potentially leading to more efficient and accurate detection of metal targets.
