 VIY2 Series GPR
The VIY-2 ground penetrating radar (GPR) is designed for the location and analysis of underground anomalies using electromagnetic pulse radiation. The operating principle of GPR is based on illuminating the survey area with electromagnetic impulses. Reflection or scattering caused by various discontinuities causes a minute signal to return to the instrument. This signal is processed and analysed to display an image representative of sub surface features. GPR is suitable for the location of both metal and dielectric targets. Strati-form structures, pipes, voids, building construction and archaeological remains.
Basic Applications:
- Tracing of underground services, utilities, telecommunications ducts and optical fibres
- Engineering construction examination (building foundations, dams, bridges etc.)
- Accident area investigation (subsidence, landslides, shaft and mine working collapse)
- Underground anomaly searches (voids, breaks, foreign objects, weak rocks)
- Archaeological Prospection
- Ground water level determination
- Subsurface deposits profiling
Key Features
- Mono-block design - all GPR modules are arranged together in a single case, which is connected to the computer via an RS232 or USB-1 communication cable
- Adjustable time variable gain control (TVGC) - amplitude control of any part of the echo signal is available
- Spectrum randomising (quasi-random sampling sequence) - interference immunity improvement, especially to coherent influences
- Increased dynamic range owing to digital stacking of received signals
- Real time signal pre-processing
- Time slice scanning window, start and stop points adjustable within 1024 samples. It is possible to acquire the GPR profile from 2nd to 5th meter, for example.
- Low power consumption - at least 8 hours working session without the need for re charging.
