It seems easy enough to reduce leakage or fuzz the signal.
I don't have the background to try to pull the limits up out of the white paper, but I think the current implementation is more or less looking for movement in 1 dimension (towards and away from the receiver). So plenty of time to decide whether radio waves are revealing anything that sight and sound are not.
