That's kinda creepy! Say your neighbour comes over to your house and plants one of these antennae somewhere, he would be able to know which room you were in!

I'm waiting on a hand-held, portable device that can scan the human body, and identify any irregularities, with no harmful side effects. (kinda like StarTrek stuff).... It's coming...

Nowhere to hide.

I have one question. Do you have a warrant? I'm sure this may have a very limited constitutional useful purposes but more than likely used for nefarious purposes and continued breakdown of our fourth amendment and constitution in general. The science is cool but how it will be used surely won't be.

Oh, I can see the Dept. of Homeland Security just eating this up.

Que perigo isso não! Qual o propósito verdadeiro desta tecnologia, fala sério....

TechHead -- as I read this no planting of an antenna in your property would be required. Just two transmitters of an inverted signal which could be on his/her property. As I think about it you might even be able to use a typical cable broadband connections which are shared amoungst a block of subscribers, as your transmitters. That is you could probably induce multiple wifi routers on your street to emit packets and with a little bit of DSP use those packets to probe the whole neighborhood. . . .

Wow low-cost interferometry for all. 8*) Once again we must trade some privacy for the many good things it brings.

Should sell like hotcakes to P.I.s everywhere! "Here is the recording Judge, subject enters, meets plaintiff, proceeds to... well you get the picture"

This technology onboard a uav yeah thats the next step i fear
