    Sweet!

    Too bad it requires Doppler effect otherwise one could map a room.
    If you sit very still, you're not detectable - but what fun is that?

    The whole idea's stupid - you design an complex expensive tracking radar system but neglect to include a transmitter and hope someone else (an adversary even) will provide this component. Why take that risk? It's like going to film someone in their home with an expensive camera and hoping they happen to have studio lighting! Nice example of technology overtaking common-sense.

    Or perhaps there is a legal reason (real radar would require a court order?)
