With the Towed Array, simplest way is to wait. Once the towed array has stabilised (that's why both move), then one will still be in the same bearing that it was before the turn, whilst the other will be at a different bearing.
For example -
Sub heading 0, 2 contacts at 90 and 270 with the one at 90 the real one. Turning to 45, after sub and towed array have both stopped moving, there will still be one at 90, however the other one will now be at 0.
Hope this helps.
As for the periscope, I'm not sure.
