I'm sure this can be annoying when people do this, but I can't help myself lol. I wonder if you could operate in a different modality and find discontinuities in material properties rather than use it as a classifier. For some reason skin cancer detection popped into my head, but general purpose inspection/detection cases for any discontinuities might be pretty helpful. Depending on the resolution/size of the field it's inspecting a realtime camera overlay might be interesting for correlation sake.
Very cool! Six years ago I worked on a mmWave (76-81GHz) imaging radar with a Rotman lens Tx and Rx. Designed as a LiDAR replacement, but we could see pipes in walls, or detect concealed weapons at ~1km.
32 port Tx (vertical pancake beams) x 16 port Rx (horizontal pancake), something like 60 by 30 degrees. the entire thing used FPGA transceivers as one-bit DAC/ADC, Complementary Golay Code waveforms with one-bit correlation in the FPGAs (two VCU128s) -- digital logic was essentially the same as a binarized neural network, I squeezed a ton of popcnt performance out of those chips using both DSPs and LUTs
So thankful the author posted this. We often learn more from failure than success. Learning from the failures of others is how we can move forward.
The lessons learned at the bottom of the article are gold.
thank you so much for your feedback, it was hard to admit defeat, but at the end looking back at what I built, the parts where I learnt about RF, and just struggled, refactoring the code for the sim (thank god cc is not good enough to understand real world physics functionning for now) were the most satisfying moments
It's a cool technology, but for it to gain commercial interest it needs to solve a problem better than the status quo. What problem is it solving and for who? If I was to buy that mmwave radar device it would probably cost more than the $60 test, and I would want assurances that it is as accurate as existing tests.
Very cool idea.

How many tx and rx antennas did you have ? (I don’t know if it was clear, my stack was 57-64 GHz, 2TX , 3RX)

Do you have a writeup about the project? I'd love to read more about it.

Was this AI comment necessary?
If you'd like to learn more about the module:

Kinda crazy that it worked but got no commercial interest. Hopefully someone suitable here sees it and can intervene
Does it also work through other materials. i.e. through a drywall etc.

love the background music in combination with the flying fishes wallpaper in the first video haha
very cool project
hahaha ! oops didn't mute the video, would blast trap music when I was alone in the lab x)
Hugged to death but I'd love to see this!
My netlify crashed fixing the website rn
just fixed it, hope it works
That's awesome. I built one for a capstone back in the day and know how tough it is to get onboarded. Kudos.
Terrific project!
thanks :) !!
