That's my fault, I was writing an email about COPPA at the same time and pasted in the wrong link. Oops!

#4We know it's simple to detect someone's heartbeat from just colour changes of ones skin in a regular video taken with a phone camera. Wouldn't this be trivial with military level IR tech? Sounds way more likely than some amazing new top secret technology that is somehow filtering out every other magnetic field and can detect a heartbeat through mountains.

#6If they can detect the faint signal of a heartbeat from so far away, why not instead deliberately transmit a weak, wider-bandwidth pseudorandom magnetic signal? Such a signal would be even harder to detect than a heartbeat without prior knowledge, yet easier to identify and track using a matched filter.

Why is everyone debating some theoretical advanced heartbeat or otherwise people detection tech rather than the absolutely obvious answer - some kind of advanced, specialized transmitter that's designed to be hard to detect and simply transmits the encrypted GPS coordinates of the pilot?

#8Back many years ago I worked on a research project which used UWB radar to detect breathing through walls / rubble / etc. But the distance was in the range of 1-10 meters. The application was to use such sensors for finding survivors after earthquakes etc.

Thanks, saved me a click.

They want to lie about how they found the soldier, and potentially have China spend a few billion trying to copy technology that can never work.
