That's not the datalink, but a Track-While-Scan radar mode. Yellow squares are enemies being tracked and red are lost contacts, i think. I (still) haven't figured out this mode completely. All I know is, it soft-locks the target, so the enemy doesn't know you're locking him and you can shoot multiple slammers into tracked targets. But you have to keep radar lock until the missile's onboard radar takes over.
Datalink are only two green friendlies, everything else is the enemy.
