What is GPR?
GPR stands for Ground Penetrating Radar, also called Ground Probing Radar and as the name suggests it is a technique for probing the ground. Like any other radar it works by sending an electromagnetic wave into the ground and recording the returning signals. These returning signals contain information about the materials, or to be exact about the changes in materials or parameters of the ground at different depths. We are using Geoscanners corp.'s georadar equipment in Turkey and outside of Turkey. You can call us or send email for your georadar job.
It is appropriate to use GPR only if there are sharp differences in the properties of the materials being surveyed. If the differences of the materials are small or their changes are gradual then the returning signals are difficult to interpret and in many cases just impossible.
GPR is well suited for geophysical applications, archeological surveys, and civil engineering applications and to locate hidden objects in the ground.
Are objects displayed like an X-ray picture?
A common misconception, mainly disseminated by Hollywood criminal television series and the like, is that the picture in the GPR control unit display presents objects as in an X-ray picture. Well, that’s not the case, the main working tool for GPR operators is the B-Scan which is nothing else than a collection of radar traces one after another in a 2D plot. (Picture on the right showing a B-Scan display of a survey)
If the picture is so unclear, why use GPR anyway?
The advantages of using GPR are many; first of all it is a relatively inexpensive way of surveying large areas without destroying or corrupting anything. GPR provides an easy way of estimating depth to layers, ground waters, bedrock,
Areas of application:
· In searching of problematic archaeological relics and residues, and wastes underground
· Preliminary study of the ground for building projects
· For danger diagnose of mining secondary damages and landslides
· In localization of underground cellars, mining galleries, tunnels etc.
· In localization of pipes, pipelines, walls etc., and also for cavities, underground waters and water springs
· In archaeology and many more underground scanning, searching and exploration.
