Abstract:Magnetic anomaly detection is extensively utilized in anti-submarine warfare and the detection of unexploded ordnance (UXO). With increasing demands for higher precision and quantification in detection, the precise localization of concealed targets using magnetic anomaly detection has emerged as a critical area of focus. Traditional methods, which rely solely on magnetic anomaly signals for target recognition, often fail to accurately determine the target"s position, making it difficult to ascertain whether the target is located directly beneath, to the left, or to the right of the survey line. Three-dimensional imaging, however, can ascertain both the horizontal position and depth of an anomaly, thus facilitating the high-precision localization of concealed targets. This paper explores the effectiveness of three-dimensional inversion for target localization based on magnetic anomaly three-dimensional imaging, through both simulation models and real-world applications. The research demonstrates that three-dimensional imaging can precisely map the three-dimensional spatial distribution of concealed targets, even at significant distances between measurement points, thereby providing robust technical support for the accurate localization of concealed targets in magnetic anomaly detection contexts.
