It really depends if its a scheduled course change or just a standard evading measure. If its evading use ure calculated AOB and add the same value as the target change course away from u to the bearing (not to the AOB). Works also in case it changes course towards u. In that case substract it.

If u wanna be on the safe side fire extra eals with same setting every 5s without updating the bearing to the target.

But if ure that close at 90 degree the standard setting zero bearing, AOB 45 with correct speed set u cant really miss.

If its a drastic scheduled course change i have no choice then to prepare a time consuming new approach.
