In order to know that the particle had tunneled through a barrier, you would have to observe it, to do that you would measure its position. Would that not destroy its chances of producing an interference pattern, whether or not the pilot wave had passed through the barrier?
You mean something like this:[diagram=663_0]If the particles come in from the left, some small proportion will tunnel through the barrier. Then it will be like a usual two-slit experiment where you see them striking the detector in the regular interference pattern. In the pilot wave interpretation, part of the pilot wave gets through the barrier and part reflects off it.
Collapsing the wave function doesn't mean that the particle can no longer tunnel.
And my best understanding dictates to me that we might consider this collapse as a destruction/absorption/using up of the wave in at least the pilot wave interpretation.
