Well, I WOULD give you a break, Ace, but you've just shoved your foot
in clear up to the knee.

The TARGET doesn't carry the beacon, you nimwad!  The beacon is out on
the range in a known location.  You then run your OTH and plot the
position of targets relative to the known position of the beacon.
This gives you much better positional accuracies on the targets, since
you now have some idea of what the error function of your OTH is
doing.

Think Differential GPS for an example of this kind of strategy.
