M-2000 radar block friendly

[borja.abadc]

It might be a stupid question, but I have a doubt about using the radar to locate a teammate with M-2000 radar. Can you lock onto a friendly aircraft to determine its position without triggering its RWR, as it would with an enemy? If we are the ones locking onto them, would they know there is no threat, and the RWR wouldn't emit a sound to initiate evasive maneuvers?

In real life, can you lock onto friendly aircraft to know their position, approach them, and fly in formation?

The only stupid question is the one that is never asked. 
 

RWR will trip regardless of whether it’s a friendly emitter or foe. But Yes, you certainly can lock up a “target” to enable closing to visual, and then fly formation from there.

Thank you very much. However, if the RWR activates and starts emitting ALERT SOUNDS because it indicates that it is being locked by us, couldn’t this cause the allied aircraft to initiate evasive maneuvers or activate countermeasures when it shouldn’t?

Does the Mirage 2000's RWR have the capability to identify that you are being locked by a friendly aircraft through the IFF?

I should test this with a friend in the simulator to see what happens. I just wanted to know if the same occurs in the real aircraft, as it does, for example, with the F/A-18, which has this capability thanks to the IFF and datalink systems.

PSID locks should not trigger anything to the best of my knowledge. They are pretty much a TWS lock so the signal doesnt change and the RWR doesnt get triggered. AI doesnt react to those locks either and wont turn on the jammer. 

 

The switch to PSIC (STT) can then be done manually or when pressing the weapons release, the system will switch to STT before firing the missile.

This is exactly why don't usually use the radar to check on a friendly for his position, but rather radio calls and navigation points

No, and honestly no RWR that I know is able to do that, at least of this era. Even the F-16C and the F/A-18C (the two most recent fighters currently modeled in DCS) cannot do that, at least considering only the RWR. As you correctly say the F/A-18C can do this thanks to the Datalink, but in a dedicated MFD page, not the RWR display.

Another sub-optimal option is to leverage the TACAN in Yardstick mode, but you would only know the distance from your buddy. You can set whatever free TACAN frequency, and your buddy will set the same channel +63 (so for example, you select 14Y and your friend sets 77Y). Then you will both see the distance from each other setting the IDN to TAC, but again, only the distance, no direction... So not very useful unless you have time to do some mental calculations.

Remember, the M-2000C modeled in DCS is an early '80s model, so you are supposed to do some navigation thanks to your brain

What @TheSkipjack95 said is also correct, PSID won't alert the receiver's RWR, but it's refresh rate is not that great.

Well, the RWR in Western aircraft, including the Viper and Hornet, very much can tell they're locked onto by a Mirage 2000. So can another Mirage. This is only a problem when both the enemy and friendlies have the same kind of fighters, which isn't the case very often IRL. Radar can be used to saddle up on your flight leader or to fly a loose trail formation, but hearing the RWR wail all the time could be annoying, so it's probably better not to do this too much.

[Galinette]

RWR cannot.

However, if you are interrogated in Mode4 IFF by a hostile, you can have IFF alarms.

Sorry, I took for granted that we were talking about DCS and not real life

Well, a realistic mission would take that into account. In fact, in such situation, without point of origin criteria (which is to say, AWACS saying "that guy just took off from a hostile airfield"), VID could become the only reliable form of IFF, and even then, you'd have to get close enough to make out the roundels. Poland didn't send its MiG-29s to at least one of the Balkan conflicts (IIRC, Allied Force), because they were also used by OPFOR, and it would probably lead to some cowboy shooting them down. Relying solely on Mode 4 IFF would be a huge gamble, one switch in wrong position at the wrong time (specifically, A/B code selector when flying at night), and may suddenly find yourself tagged as a bandit.

Also note that Soviet doctrine of strict GCI control would have had advantages in such situation, since the GCI likely knows which contacts are its own fighters. At night especially, it could even force NATO to adopt a similar doctrine at least with regards to any hardware shared with the enemy.

[=36=Witcher]

All correct. But the question was: Can the RWR tell apart a friendly from a bandit on its own? The answer is no.
