Ground Penetrating Radar using Arduino

Similar projects worth following
This project developed a very low cost (under 300 USD components cost) Ground Penetrating Radar. The acquired data can be visualized onboard, in real time, as well as stored and transferred to a PC for further processing.
The digital section uses an Arduino Mega 2560 board.
The onboard visualization uses an LCD shield for Arduino Mega 2560.
The analog section is custom built.
The frequency range is 323 MHz - 910 MHz.

The construction and software files contain the complete information for building the project.

    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.

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.

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 .

@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?.

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?

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 !!

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.

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.
