OkeeDokee....Hypothetically....
If any ship were to deploy two towed arrays at the same time (as in the dual towed array systems being developed by some navies), then hypothetically both towed arrays together would be able to detemine "true bearing" to the contact without having to undergo ship course changes. The signals detected on the TA would just be time compared (to see which TA is seeing the signal a fraction of a second before the other, that TA is toward the real contact and not the mirror).
That being accepted as true.... shouldn't submarines be able to deploy both their TA to eliminate bearing ambiguity?
I have a theory that some subs do this already....... related to a theory that I have that the SW and VA actually have more than 2 TA (perhaps 3 - 4, and that is the reason it has 2 seperate TA fins instead of streaming the TA from the aft control surfaces like previous designs).
Therefore... I vote all US subs TA have their "mirrored contact" stats removed.
