How is AIM-120 guided by the datalink in DCS?

I found that this is mentioned in the change log of version 2.7.7.14727 Open Beta

AIM-120 AMRAAM has received a separate INS (Inertial Navigation System) unit with datalink support. 

But I couldn't find relevant discussions on the forum, nor did I find relevant instructions elsewhere. I heard some people say that after the launch of the AIM-120, if the missile is unlocked before the missile radar is turned on, the missile can be corrected through the datalink information on the aircraft. Is this statement correct?

A simple, to the point answer:

The missile 'datalink' is kind of a misleading name, the -120C doesn't have the capabilities of the -120D that can be guided by other aircraft for example. The way it works is that the actual radar wave on the launch aircraft has encoded commands for the missile itself, a computer on board the missile interprets these commands and updates the steering. The datalink in DCS aircraft (Link-16, SALD, etc.) have nothing to do with the Amraam. The INS ensures that the missile even without steering commands from the radar tries to guide itself to a computed point of likely intercept with the target.

During the AMRAAMs midcourse phase, it can receive corrections from a data link (note, this is not a tactical data link, its a specific data link for the AMRAAM), transmitted from the RADAR. This requires the firing platform's RADAR to have a track on the target.

If the aircraft loses the track, the AMRAAM will guide on the last calculated intercept point (not sure what happens if the track is reestablished, whether midcourse corrections will resume or not).

I'm also not sure if the firing platform's RADAR will continue to transmit data link commands (using the last calculated intercept position as calculated by the firing platform, though this is probably redundant seeing as the missile does it).

Thanks I get it

Your question is also my question all the time. The verification of these problems requires another player to accompany me to repeat the test. Unfortunately, I can't find anyone to test together, and I don't have so much time to test.
