As you may or may not know Jane's A/F-18 Hornet simulation, which is famous for its faithful recreation of the plane's avionics and systems displays incoming SAMs on the HUD. Even though the pilot cannot see the missile there is a red bounding box around it. I thought about it for a while and decided that such a thing is not possible in real life. How can the fighter's systems track the trajectory of a MACH 3 missile and what it's doing? If the weapon uses an active or semi-active radar guidance the fighters warning systems can intercept and analyze the various radio frequencies emitted by the ground-based (or missile-based) guidance equipment. The pilot will know that a hostile radar is tracking or guiding a weapon, but will never know what the missile is doing unless a data link between the missile and its target is sending the missile's flight parameters to the fighter-an absurd idea of course.

Not as absurd as you may think. Missile Approach Warning Systems (MAWS) have been beein in service for quite a while. While originally they were fitted to HVA aircraft and later to strike assets (F-111 for example), they have lately been spreading to tactical fighter aircraft. There has also been a gradual shift from the original IR-detecting systems to MMW-radar ones, now that the technology for that section is maturing.

I should point out, that the majority of these systems warn for astern threats, with side-coverage possible in only a limited series. I am not aware of any system that can provide front coverage, as you imply. Maybe that was just a "SA enhancement" to model the fact that an incoming missile is often a _very_ distinctive sight.

The system on the Su-24 does provide 360deg coverage, but its capability at descriminating incoming missiles is limited i believe to close ranges. It was this system that formed the basis of the Su-35 MAWS. The coverage is limited to mainly to above for the Su-24, while a much more advanced system is avalible on the Su-35.

An incredibly useful tool as the hardware gets minitiurized, and the software interpretin` the signal matures...if you ask me...

New generation fighters like the Rafale and SU-34 are reportedly able to not only track but also destroy {with their own AAMs}incoming missles that fall within their main sensor cones, which in the SU-34's case means rear aspect as well thanks to it's rear facing secondary radar.

My knowledge of this all stems from my ancient flight experience with Falcon 3.0 and my trusty Threat Warning Indicator.

Small diamonds are missiles, where they are in the TWI depends on where the signal is coming from. The stronger the signal (which can mean the closer the missile is), the nearer it is to the epicenter which represents my aircraft.

IR guided missiles can't be detected through the TWI but the warning indicator still lights up. Its time to boogie and start flaring while switching to padlock.

Its possible that if the missile has active radar that its position could identified by an RWR, and relay the information to display on the HUD. If the missile is not active radar guided, it wouldn't be able to track the missile itself, but the radar site itself coud be, which may be near the launch site.
