a) if you're using anything close to the usual
time/distance/acceleration scale, the time lapse for signal generation
and return is significant to fire control, but not to the commander's
observation/decision/action cycle.  The generally accepted scale is
15min/1000km, so you can ping & detect anything up to 150mu away in one
second and have plenty of time to decide what to do.
b) what matters is how far he moves between the time the signal reflects
from him and the time you receive it--that is your "circle of
uncertainty".  It doesn't matter whether the source of the signal is you
or his own noise.
