What are the capability of 2 way datalink on air to air missile?

[Ronny]

Certain air-to-air missiles, such as the Meteor, AIM-120D, and Derby Mk-III, are equipped with a two-way datalink. This capability allows the launching platform not only to provide mid-course target updates—such as heading and speed—but also to receive data from the missile itself. But what information can the missile send back through the down link ?. While parameters like the missile’s own speed are relatively straightforward, can the missile also relay data gathered by its onboard seeker, such as targets it has detected or is actively tracking?. In other words, could the missile act as mini radar sensor for the aircraft?

as you said, the missile seeker actually can be Jet sensor.

For example, the F3 version of the Rafale has the IRST sensor in the FSO removed. Before the missile is launched, it uses the infrared sensor of the Mica to achieve infrared detection and tracking functions.

But generally speaking, missiles need more situational awareness than fighters. Fighters can provide much more information than missiles, and missiles need to reduce their detectability.

That's through the wiring before launch, not through the 2-way radio datalink.
