Method for detecting targets using a metal detector
The 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, with the output being influenced by the estimated properties of these targets.
Additionally, the patent describes features that improve the functionality of the metal detector. It includes modes for general detection and pinpointing, allowing users to swing the receiver or move it closer to specific areas of interest. The audio output can be modulated to reflect the proximity and identity of targets, and it is engineered to minimize the impact of height changes during pinpointing. The method also incorporates techniques to reduce unwanted noise and discriminate between closely situated targets, enhancing the overall detection accuracy. Furthermore, the patent specifies that a non-transitory computer-readable medium can store instructions for executing this method, indicating the integration of advanced processing capabilities within the metal detector system.
