Borehole Radar Interferometry

The knowledge of subsurface structures ahead of mining, in 3D and with high resolution, is very useful for<br>efficient mine planning and economic assessment. Three dimensional orebody geometry estimates derived<br>from coring never have sufficient detail, due to lateral inhomogeneity. We are investigating whether a<br>Borehole Radar Interferometric imaging method can produce very high resolution 3D images of the<br>subsurface, with a resolution of the order of 1 metre. Our method is based on Synthetic Aperture Radar<br>(SAR) technology.
