What is GPR system?

Ground Penetrating Radar (GPR) is a real-time NDT technique that uses high frequency radio waves, yielding data with very high resolution in a short amount of time. This technique uses electromagnetic waves that travel at a specific velocity determined by the permittivity of the material.

What is GPR report?

Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables or masonry.

What are the properties of GPR?

GPR energy is EM (electromagnetic – ie “radio”), therefore physical properties that affect the survey are electrical conductivity and dielectric permitivity. Results are usually presented similarly to seismic data, as position versus 2-way travel time.

What is the accuracy of GPR?

GPR is 100% accurate While GPR is one of the most effective forms of non-destructive testing, it is not 100% accurate. The variables we have discussed here such as the conditions and material of the scanning area, along with the person using the equipment all affect the accuracy.

What frequency is GPR?

1 to 1000 MHz
Penetrating Radar (GPR) is the general term applied to techniques which employ radio waves, typically in the 1 to 1000 MHz frequency range, to map structures and features buried in the ground (or in man-made structures).

What affects GPR?

To recap: How deep a GPR signal goes beneath the soil surface depends on soil conditions, the antenna used, and the size of the target you are scanning for. Each of these major factors will play into the depth penetration capabilities of your system.

Can GPR detect plastic pipes?

Pipes. GPR can detect pipes used for utilities and other purposes, in all sizes. Metal pipes are most easily detected due to their strong interaction with the radar signal, though GPR can be used to locate all variety of PVC and plastic pipes as well.

How does GPR scanning work?

Ground Penetrating Radar (GPR) uses a high frequency radio signal that is transmitted into the ground and reflected signals are returned to the receiver and stored on digital media. The computer measures the time taken for a pulse to travel to and from the target which indicates its depth and location.

What does GPR mean?

IDS is the leading supplier of multi-frequency and multi-channel ground penetrating radar (GPR) designed for non-destructive testing and geophysical investigations.

What is IDs georadar?

Radar for Mining Applications IDS GeoRadar is a leading supplier of robust, reliable and user-friendly radar systems, including slope-monitoring radar and ground-penetrating radar for mining applications.

What’s new at IDS?

IBIS have introduced a slope monitoring radar system able to resolve the spatial direction of displacement over hundreds of thousands of pixels, in real time. IDS is pleased to present IBIS-FB, the new IBIS radar for broad area monitoring of blast-induced vibrations.

Why choose IDs radars?

Currently, the most prominent international mining groups choose IDS radars for their reliability, robustness and unrivalled performance.
