Hello,
Thank you for designing this project. I tried to make the cards by buying the PCB on JLCPCB but some layers are reversed. This is probably due to an export error from Orcad.
Can you provide the design in ODB++ format please ?

Hello, I couldnot find .opj file for the RF? Could you please upload. Would really appreciate 

hi can anyone give an approximate estimate of depth penetration in soil ?

Good evening, I noticed in the diagram the components LMV772 and MCP4725, in the photos the 772 has 6 pins but they only exist at 8 pins.. while the MCP4725 has 8 pins in the photo but I can only find them at 6 pins.. what was mounted on the card instead of the ones in the diagram? can someone help me? what did you mount on the card? do you have any alternatives for me? Thank you.

Hello everyone, my name is Hamdallah, I am from Afghanistan, thank you for sharing your project
I have a problem in the uploading part of the program and an error during uploading. includ Arduino fft.h. I couldn't do anything with all my efforts

Hi , use the manage library command , search for fft then   add arduinofft, Use 1.62 I think as the latest errors out. I've just started looking at this [project,

Hi,

What is the license of the project, I mean, could I reproduce it (or part) for educational and non commercial purposes?

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

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 ?

Hi!

Is there anychance that i could buy this 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.

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

use Matlab spectogram

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

1) https://imgur.com/a/1kmBsni

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...

your link is not alive, renew plz
