Ground Penetrating Radar (GPR) is a non-invasive geophysical technique applied to investigate the subsurface. It works by transmitting electromagnetic waves into the ground and analyzing the reflected signals. These reflections provide information about the existence of different strata at varying depths, allowing researchers and engineers to generate subsurface images. GPR is frequently used in a spectrum of applications, including archaeological investigations, utility mapping, and environmental remediation.
- Implementations of GPR include detecting buried objects, examining soil conditions, and mapping subsurface formations.
The precision of GPR systems varies depending on the frequency of the electromagnetic waves used and the characteristics of the subsurface strata. Advances in GPR technology have led to improved visualization, allowing for greater penetration depths and better detail in the images.
