Would the Strela not lose its lock if you dive to the ground?

The strela as known can use to kind of tracking to find its target
one is IR and one is TV as i understand it
im always told that the strela missile never lose lock cause it has tge TV lock so you cant flare it

but should the strela then not lose its lock if you fly with either hill or ground in the background of the missiles tracking if its using the the TV tracking?
would the trees and ground not confuse the tracking?

Lose lock if you are flying low and the missile is above you. Then the ground is like a background, and the missile does not hit. If the missile was fired in photocontrast mode ofc.

It selects the mode before firing, and cannot switch between IR and Photocontrast during flight.

It will automatically switch from contrast-detect to IR to my remembrance, if you continue flaring and try to dodge it like a 9M you’ll be golden.

It does not. Once you fire, the mode selected is how it will track.

Yes. Though i think once it gets close enough, it doesnt matter.
