Precise Magnetometers for UXO & Ferromagnetic Objects

Precise magnetometers for UXO and ferromagnetic objects are high-sensitivity magnetic field measurement instruments designed to detect unexploded ordnance, buried metallic debris, and ferromagnetic material concentrations in post-conflict terrain, humanitarian demining operations, and contaminated land assessments. These instruments measure distortions in the Earth’s magnetic field caused by ferrous metal masses, allowing operators to locate and identify buried threats without excavation, reducing the time and risk associated with manual search methods.

Fluxgate gradiometer configurations using vertically separated sensors achieve detection sensitivities below 0.1 nanoTesla, sufficient to locate small UXO items including anti-personnel mines and buried artillery shells. The gradiometer’s automatic cancellation of large-scale geomagnetic field variations isolates localized anomalies from target ferromagnetic masses, improving detection reliability in areas with significant magnetic background noise from natural iron-rich soil or surface metal contamination. Detection range for a standard anti-tank mine reaches depths of 1 to 1.5 meters under favorable conditions. Smaller anti-personnel devices detect at shallower depths of 30 to 50 centimeters.

Survey methodology employs systematic grid-based coverage with sensors held at consistent height and orientation along parallel scan lines spaced at regular intervals across the suspected contamination area. Real-time signal monitoring allows operators to identify anomalies during acquisition, marking probable target locations for subsequent manual excavation or mechanical removal. Data logging with GPS integration creates archival records of survey results for documentation and comparative analysis if resurvey is required following clearance operations.

In Pakistan, magnetometers for UXO detection support humanitarian demining operations in KPK and Balochistan regions affected by conflict activities, military EOD teams clearing ordnance-contaminated training ranges, and civil engineering teams assessing ferromagnetic contamination before construction projects in areas with past military use or munitions manufacturing activity.
