System tested on a bridge. This is the GPR image obtained for the bridge in the photo:
System tested and works fine.
Antenna coupling is quite high. Would be nice placing the antennas at a bigger distance from each other, or using more directive antennas in order to reduce unwanted coupling.
This is how the electronic boards are stacked.

Hello. Can you post all the documentation of this GPR project? I need inter-board connection project.
thanks.

hi i am doing this project and i am stuck with antenna part , idk how to do it! if anyone can help that will be amazing.
Hi , I would like buy also all the project from you ?
Smaller compact Vivaldi array to try https://imgur.com/a/zWIoyvj
the dimensions are 130mm x 120mm x 20mm for the dual substrate (idea is to use 2 single sided pcbs with epoxy filling in between, maybe expandite foam {lightweight} ) . or just use standard double-sided pcb. BW= 250 - 10000 MHz Gain ~17dB.
You can read more on Vivaldi antennae here & have fun making your own to suit your purpose.
https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=9017985
In the range. https://bit.ly/uwbant (colour black) & https://bit.ly/730MHzuwbant (colour blue)
Keen on doing your own, you must understand about the substrate (FR4 or similar ~120mm ~130mm cost is around ~$700 & you need 2 of them (antennas), here, just quickly with pictures, https://imgur.com/a/e4Y8KRC .

also you provide an link "https://imgur.com/a/zWIoyvj" i cant find the sizes to create the pcb
@miricip This project right to go, I have found board shop that will make the RF&LF board for me (i could do myself but lack the time etc.) They will assemble also, so it`s just a matter of connecting to the arduino mega. roughly quoted @ 100usd per board just upload the 2 zip folders LF & RF. (https://bit.ly/project_pcbs). Someone else stated/questioned the 100k pot, doesn`t quite match the silkscreen. albeit, one of the resistors {2 in that group of components} (which one) could be replaced with a variable resistor (make an earth connect) right?.
Did you have the boards built and assembled? How did that go? What was your solution for the Vivaldi array?
Hi any other visualization software work with this? labview2013 not obtainable even on community download. OR VI converter? . looked at snuffler (works with gradiometer well) and https://www.gpr-archaeology.com/software/ but as I haven`t built it yet IDK. thanks
Hello, I would like to make the project, but I can't find some things in the diagrams, 1) how the LF board is attached to the Arduino.. on which pins? 2) I see 4 resistors under the Arduino, where are they soldered? 3) in the photo of the LF card there is a 100k potentiometer that I can't find in the diagram.. can anyone help me? I would be grateful to you.. nev100celle@hotmail.it

2) check the connection image, connect diag. png in the list of 8 files. (digital pins 3,5,6,7 )
3) quizzing that myself, swap a static resistor for adjustment perhaps, there`s 2 in that area going by the silkscreen, on the picture i see variabe resistor 3 legs, looks like only 2 are used, go with the schematic /bom values & silk placement perhaps?

Thank you Can you add the gerber file for the pcb print please
Ciao Mirel, great project!!! I am trying the setup, but before spending on double side PCB i am simulating antipodal Vivaldi antennas radiation pattern. In that sense, even if shape is clear from file, would be great to have some clarification on antenna geometry, specifically on its dimension. Also it is not very clear from the gallery if PCB used is flexible and the antennas best position. Can you please help us somehow with more detailed picture/scheme or something else?
Thank you a lot and again, my compliment for the incredible project !!
hello .

great video Nouh, if i can ask to you, what are dimension of double sized PCB you used? 15cm x 25cm...
Sir, how do you make a 3d that tries to take care of things under the ground. Please make something like that. It is very valuable.. diagrams and. Will you make a video showing all the equipment... we hope. For example, secret imager 3d, (uxo mini underground imaging detector), easy way detector, produced by Adrenaline Company, can be named...they are umbrellas. Easy to use. How to make such a device.. Do the project and show it. Good luck to you, happy for you.

can anyone tell me they created this in the states
Thanks
Hi Mike;
Just a thought:
Do you think most of the RF and display functions could be performed using the very cool "tinySA" spectrum analyzer, (about $70 us)?
It has a built in RF output port that can track, with or without offset, from the input port. It can be controlled through a USB cable and display on a PC.

Can anyone please tell me the purpose of the GPR_JF board?? What does it do??
