GPR works on the radar principle, but underground, transmitting pulses of radio wave energy into the ground and measuring their reflection to create a cross-section image of different material layers, boundaries and objects under the surface. It is also used to identify cable routes and pipelines beneath the ground using a combination of non-invasive and non-destructive means to identify underground features.
Different radio frequencies are used for different applications – higher frequencies give higher resolution data at shallow depths, and lower frequencies can be used to get information from deeper areas below the ground.
