Thanks great presentation,I am geologist also working as Geotechnical Engineer. Can we use GPR in hilly area or over mountains for exploration of heavy metals.
Thank you for sharing valuable technics. I am interested in 3D GPR system of Senors & Software to detect Cavity 2.5m subsurface. Do you sell any 3D GPR sytem or antena? Do you have off-line training course to recommend?
Not in my experience. It is difficult to “direct” GPR signal. You can sometimes see that you are approaching an object by seeing the start of the hyperbolic tails, but imaging a target requires the antennas to pass overtop of it.
Very informative. Are there any tips to identify between type of material For example a Cable , a Metal Pipe vs a Plastic Pipe vs a Cement Pipe. Or a Plastic Pipe containing a cable, Optic Fiber Etc.
We can't identify the material of the pipe directly. But a non-metallic pipe will have a weaker reflection than a metal pipe, if they are at the same depth and roughly the same size.
Yes, see this video of a cave detected in limestone rock at a depth of 6m: ruclips.net/user/shortsrJLmqR4VqUw Also see a recent webinar where I talk about finding voids with GPR: ruclips.net/video/tV23uqpCqcw/видео.html
GPR cannot distinguish between types of metals. However, if the object is non-metallic, it will have a slightly weaker signature. Also, you can sometimes tell the material composition by looking at the polarity of the signal. In other words, the top band of the hyperbola might be black for a metal object, but white for a plastic object. In practice though, this isn’t always easy to tell
This was a great presentation.
Thank you for watching the webinar!
Thank you for this valuable information
34:13 the air wave reflection off a building is not 1/c slope?

can we use another kind of antenna to push the signal only to one side?

Thanks so much @@sensoftgpr

Has anyone had a survey on tunnel in the rock layer?
Yes, see this video of a cave detected in limestone rock at a depth of 6m: ruclips.net/user/shortsrJLmqR4VqUw

This Very Educational. Is there a possibilty for me to get this powerpoint file?
thank you for contacting us. Please send your request to Sensoft_training@spx.com
Is there any way that i can know the type of the metal or whatever the thing under the ground based on the hyperbole?
