I remember that a guest in a Joe Rogan podcast told about military technology that can "see people through walls." I wonder if it is related.

An anecdote, I had this radio that would produce static if I walked in front of it. Others before me must have had the same experience and deducted what was to become the technology you just described.

Lastly, your article also reminded me of the technology that can recompose what you are watching on your screen just by detecting its radiation.
