With ground
penetrating radar Precision Locating's technician can see a pipe or cable in its topographical
context making it ideal for locating and excavating utilities. The advantage over a traditional, electromagnetic locator is
that ground penetrating radar can see non-conductive materials including plastic, clay and cement pipes.
This type of specialized radar
works a lot like regular radar. The radar
unit has a sending antenna which sends out pulses of sound, and a receiving antenna, which picks up those pulses when they
bounce off objects underground. The returned pulses can be used to construct an image of what is underground, because they
will vary depending on the depth and composition of buried objects.Several factors influence the usefulness of ground
penetrating radar.
The first is the nature of the ground being examined, and what is being
looked for; subtle geological differences, for example, can make it hard to get an accurate picture. The strength and frequency
of the signal also makes a difference, as does the conductivity of the ground.
Some types of rock and soil conduct sound better than others, generating a clearer picture.
