Figure 2-11: In Line Scan mode, the PCD profile appears under the GPR Line image. The PCD profile also appears
after collecting each line in a Grid Scan.
With Grid Scan data, the PCD responses from all the grid lines are combined together to
generate a map image of the magnetic field strength at the surface caused by flowing current
(Figure 2-12). This image determines the position and location of the target but, unlike GPR
depth slices, there is only one PCD image and it is not possible to measure how deep a target is
based only on its PCD response.
Figure 2-12: After Grid Scan data have been processed into depth slice images, the PCD image can also be
displayed.
