Improved interpretation of borehole radar data through interactive 3D forward modeling

Borehole radar is being applied to delineate tabular orebodies in South African gold and platinum mines. The radar<br>is omni-directional in azimuth, leading to an ambiguity in the direction to a reflector. One way of resolving the<br>directional ambiguity is through the use of a priori information. The regional dip and strike of the orebody are<br>known, and can be used as a first approximation for the position of the reflector. A program called Fresco has been<br>developed in which a candidate orebody can be manipulated, and its radar response can be modelled in real time.<br>The model can then be manipulated until the modelled response agrees with the measured response.
