"Magnetic Multi-Target Simulation and Field-Measured Dataset"

"This dataset provides high-quality simulation and field-measured magnetic data dedicated to the research of magnetic multi-target recognition and localization, especially for complex scenarios with dense distribution, small target spacing, and strong magnetic field coupling. It is constructed to address the key challenges in existing magnetic detection tasks, including missed detection, false alarms, and inaccurate positioning caused by overlapping magnetic anomaly signals of adjacent targets.The dataset consists of two parts: simulation data generated by the standard magnetic dipole forward modeling theory, and field-measured data collected by a high-precision three-axis fluxgate magnetometer in real experimental environments. It covers diversified configurations, including targets with different magnetic moments, different burial depths, various horizontal positions, and dense arrangements with small intervals. The core data components include the vertical magnetic field components at two measuring heights, magnetic gradient tensor information, target real position coordinates, and binary mask labels that mark the effective target areas. All data are organized in a standard grid format (18\u00d718), which is convenient for direct reading and processing."
