You have it wrong.
The AIM-9X tracks the brightest, largest blob of pixels, together with some additional filters (motion tracking etc); there are films of seeker footage on youtube.
The ground is almost always colder or at least farther away, so the aircraft will almost always be the brightest collection of pixels.
That's just the very basics of it all as I understand it.

Or am I getting it wrong? Cheers.
