Figure 2-3: Crossing a rebar perpendicularly produces hyperbolas in the GPR Line image. The location of a target
corresponds to the top or apex of the hyperbola, as shown by the red arrows

2.2 Line Scans Running Parallel to Targets

Moving parallel to (or directly on top of) the subsurface feature (Figure 2-4) results in a constant
flat line in the data image (Figure 2-5). Other features such as layers and the bottom of concrete
will also appear as flat responses.
Figure 2-4: The red arrow represents the path of the sensor, running on top of a rebar or conduit.
