The Jammer switching off was my guess at first too.
I tried it with the SA-10. I closed in to about 10 - 15 nm using terrain masking and then I executed pop up maneuvers to provoke it. When the SA-10 fired I would dive and hide in the terrain to mask the Flap Lid. Even in jammer mode 3, the missiles lost guidance as soon as I broke the lock to the Flap Lid.
Here they still have a lock on me:
Here they lost it, when the Flap Lid became masked:
The missiles still have a clear line of sight, though.
I remember an instance in 4.35 or 4.36 (not sure anymore) where I did such pop up attacks with HARMs on SA-10. I dived for the deck and masked the radar, but then I could see a missile still guiding on me and realised I had my jammer on. When I turned it off, the missile immediately lost track and passed behind me.
This does not seem to be the case in 4.37 anymore.
