Method for detecting targets with a metal detector
The granted patent US12025766B2 outlines a method and system for enhancing target detection using a metal detector. The method involves transmitting a magnetic field and determining the positions of the metal detector's receiver as it moves. The receiver captures magnetic fields resulting from the transmitted signal, generating receive signals that are analyzed to estimate properties of targets. Notably, this estimation relies on multiple receive signals from various positions, ensuring that the analysis remains largely unaffected by other nearby targets. The system is designed to produce an audio output signal that conveys information about the detected targets based on the estimated properties.
Additionally, the patent describes features that improve the functionality of the metal detector. It includes modes for general metal detection and pinpointing specific targets, with the audio output tailored to indicate the proximity and identity of targets. The method also incorporates mechanisms to filter out noise and enhance target discrimination, particularly in scenarios where multiple targets are close together. Furthermore, the patent specifies that the system can be implemented through a non-transitory computer-readable medium, allowing for programmable control of the metal detector's operations. Overall, the patent presents a comprehensive approach to improving target detection accuracy and user experience in metal detection technology.
