Examples

The next examples are real and everyone can test it.

1. Photo and result of a little cave: width 1.5m, length 2m, height 0.8m, the ceiling is 1m deep from the surface.

2.Photo, result and plan of the cave: width 1.5m, height 1.8m, the ceiling is from 1.2m to 4m deep from the surface.

position b - the ceiling is 2.2m deep from the surface

position c - the ceiling is 3m deep from the surface

position d - the ceiling is 4m deep from the surface

3. Cave ( width 0.4meters, length 0.8m, height 0.25m ) in a rather dry soil without clay on the depth 0.5m , covered with a plastic flatness 0.9m x 0.5m x 5mm - non conductor , (tested that GPR can not detect the flatness in air, can not detect difference between air and flatness)

antenna - 300 MHz

time window - 50 nS
