GROUND PENETRATING RADAR

Ground penetrating Radar (or GPR) – is a non-destructive method for subsurface reflections investigation. A short electromagnetic pulse is emitted to the environment, when the pulse reaches the layer (or an object) which relative permittivity differs from the environments, part of pulse reflects and the returns to antenna, the other part goes on, until it reaches the next layer (or object). In general, any dielectric discontinuity can be detected.
