We were cleared for a visual approach with a left base entry to Runway 28L at SFO after reporting an air carrier jet in sight approaching the parallel Runway 28R from the east. We turned a 15 mile final and intercepted the localizer for 28L for which we had verified the proper ident. My First Officer indicated the air carrier jet looked like it had flown through 28R's centerline toward our course. I offset our track to the left to provide some additional spacing. We then received a climbing TCAS RA which I executed. We received a clear of conflict and the First Officer reported the TCAS climb to ATC; who asked if we were able to continue the approach. We responded that we could still continue the approach and I began to correct our vertical path to recapture a stabilized profile. I asked the First Officer if he could see the air carrier jet; which he responded he could not. As I asked this question I scanned my EFIS displays noticing traffic apparently on our same approach course below us. I received another TCAS RA and executed a missed approach.It's possible the air carrier jet erroneously intercepted the localizer/final approach course for 28L instead of 28R. In fact; I believe it was eventually cleared to land on 28L as we executed our missed approach.
An air carrier Captain reported executing a missed approach on a SFO Runway 28L visual after the second TCAS RA climb command from another aircraft which apparently erroneously lined up on 28L instead of the assigned 28R.
