This technology is going to have a direct negative impact on my life at my next family gathering, when my uncle tells me the government is probably using this to spy on him.

Just say "pfft, you believe in the government?"

No such thing as the government, that's just a thing invented by big news to sell you more news

Inferometrics are kind of nuts.

Without even reading the paper, I'll bet they are basing this on the work Katie Bouman did with her developments for black hole imaging.

What makes you think it has anything to do with Katie Bouman's work?

Well if you've ever check out her yt channel and grad work: https://m.youtube.com/watch?v=EfGvPinTJU s, the suspicion might begin to reveal itself.

Her grad work involved inferometrics and corner cameras. Then there was a series of papers using lidar to image around corners that also drew on her work.

When I read about her work on the CHIRP algorithm, it occured to me there was quite a range of interesting practical applications around it (at the time I was very interested in full waveform lidar). Many lidar systems allow for multiple return counts. If you have multiple shots into a single physical space, you can think of the shot vector as being in frequency space. Build up enough shots into a single space and while it's not traditional inferometry, you can think of the result as an interference mire typical from something like infsar

Sounds like that recent captain d video about deblurring gaussian blurred images
