Detection of Uxo and Landmines Using 2-D Modeling of Geoelectrical Resistivity Data

Buried landmines pose serious hazard in more than 60 countries across the globe. Recent<br>estimations suggest as many as 110 million such objects lay worldwide. Detecting these mines with<br>standard metal detectors is difficult, as many are comprised primarily of plastic, with often only a firing<br>pin as the sole metallic component. The development of geophysical methods for unexploded Ordnance<br>(UXO) detection has been underway for almost ten years, and arose in the international context from the<br>need to rapidly characterizing large areas of potentially UXO-contamination.<br>In this work, the geoelectrical resistivity could be one of the most useful parameters to<br>discriminate ordnance types, shapes and locations especially near the surface. This study represents a<br>successful trial to adopt the geoelectrical resistivity technique for detecting buried UXO and other clutter<br>environmental noise. A forward and inversion routine had been adopted and applied to synthetic<br>resistivity models for different UXO and landmines. In addition, models of non metal ordnance had been<br>used, and were successfully detected. The obtained results show high efficiency of the technique to<br>image those models. Now we are trying to adopt the technique to work in the filed, hence apply it for<br>test site.
