Georadar, or GPR (Ground Penetrating Radar), is a noninvasive geophysical survey technology used for subsurface exploration and structure diagnostics.
The method is based on the emission of radio-frequency electromagnetic pulses by a transmitting antenna. As these waves pass through materials, they are partially reflected and diffracted at physical discontinuities (changes in dielectric constant or electrical conductivity) and detected by a receiving antenna. By analyzing the time and intensity of the reflected signal, information on the nature, depth, and geometry of the objects or layers passed through can be obtained.
