Why Modern Techniques?

• Labor Intensive

• Time-consuming

• Expensive

• Dictated by conditions (time of year, sun angle,

weather, etc.)

• Approachability

• Safety of the Personnel

GPR (Ground Penetrating Radar)

• Uses Electro magnetic signals to locate buried objects

• Many diverse designs and operation methods, but works with transmission of

electromagnetic energy (usually a pulse), and the detection of a small amount of

that energy reflected from the target

• The time delay of the reflection contains information on the range of the target.

SYNONYMS

Ground Probing Radar

GeoRadar

Surface Penetrating Radar (SPS)



The round-trip transit time of the pulse emitted by the GPR and its reflection provide range information on the target
