The VIY3-300 ground penetrating radar (GPR) is the main workhorse for deeper than sub-surface imaging. It is designed to map out foundations of buildings, basements, crevices in the ground, pipelines, cables, and sub-surface oil contamination. It is used for location and analysis of underground anomalies using electromagnetic pulse radiation. Operation principle of the GPR is based on surveying media illumination by electromagnetic impulses with following echoes analysis because of impulse reflection or scattering by various discontinuities. The GPR is suitable for searching of both metal and dielectric targets (stratiform structures, pipes, voids, building constructions etc.).

  • Determination of boundaries of petroleum contamination

GroundPenetrating Radar VIY3-300

Basic applications:

  • Engineering and communication objects searching
  • Engineering construction examination (building basis, dams, etc.)
  • Man-caused accident areas investigation
  • Underground anomalies searching (voids, breaks, foreign inclusions, weak rocks)
  • Search of liked sources from pipes. By Indirect attributes (area of the raised humidity)


  • Monoblock design – all GPR modules are arranged all together into a single case, which is connected to computer via USB2 communication cable.
  • Spectrum randomizing (quasi-random sampling sequence) – interference immunity improvement especially to coherent influences
