| Description | BACKGROUND:
Mining and Gas/oil exploration have led to great technology advances in detection of anomalies underground. Geologist can “see” pockets of materials through thousands of feet of rock. This usually works because there is a great contrast between the background (rock) and the target (oil). Also the “pocket” of target material is usually quite large as well. Even with all this technology, however, it is still difficult to consistently find a void or “hole” below ground.
There is a need to detect underground voids and tactical tunnels as deep as 100 feet below the surface.
