Very low power transmitters are actually legitimate, at least in some
bands, so you don't have to drop the signal to the point where it'd
merge seamlessly with ambient noise.

However I doubt that extremely low power transmitters will accomplish what
is desired.

I also wonder whether extremely low data rates are desired.

Different topic. Try "phase conjugate mirrors" in optical and physics
journals. I'm not positive that this would be good enough to help avoid
detection.
