The newer ones, like the "big" SA-20, might be able to do it, but it
would still be a fairly tough targeting solution - you'd need to loft
one up before the SR-71 was in range, then acquire it while in midair.

at which point in time, couldn't the 71 see it coming, and maneuver
to make the geometry as bad as for the others?

At those speeds and heights, it's like trying to skeet shoot cannonballs
from behind after you see the flash from the cannon.
