Ground penetrating radar (GPR)

Ground penetrating radar (GPR)

The aim of the GPR project is to use radar radiation to view the interior of various optically opaque objects and to generate three-dimensional models from the data.

Procedure:

A broadband RADAR signal is transmitted to the material under investigation via special antennas. In the event of impedance changes - such as occur in the case of impurities - the beams are reflected and refracted in accordance with the laws of high-frequency technology.

 

 

The reflected rays are received with a receiving antenna and electronically isolated. With signal processing, the received data is combined into a 3D image and can then be viewed in a 3D visualization program. The above pictures show the raw data for a metal ball, which is slightly elevated above the ground, in a 3D view.
