[MISSING TRACK FILE] RWR spurious lock tone

raelias · June 27, 2019

Hi guys,

I'd like to know if anything is beeing done about the rwr, everytime I a buddy gets locked, even if dozens of miles away in different azimuth when I am on the ground i get a locking tone on the RwR and vice versa, it's really annoying and a huge problem to situation awarness specially when you are in the mix, do you get this as well? this has been going on for many months now without a fix

I dont think so its bug.

I get it. I haven't done proper testing on it, but I think it might occur when I'm in the same azimuth from the locking radar as the aircraft locked. I guess my RWR would pick the difference in wave pattern as well, since I'm in the same azimuth and thus in the small cone that the radar is focusing on.

If the above makes sense and it's realistic, OK. If it's false, then it's a bug.

And you're right, it's pretty annoying for SA.

It's a long time bug I am afraid.

It is not a big and intended probably. See F14 forum where va HB de explains in détails why F14 also has the same behaviour

The only thing that makes me think this might be a bug is the fact that it happens only for lock on warning but it doesnt happen for launch warnings. So if we were talking about simulating a narrow wave pattern that somehow "touches" our plane in the way then we should hear both warnings, and as I said we only hear the lock on one.

Hope it has something to do, I might be wrong.

If that's true, then I agree it's a bug. I don't recall if I get a launch warning as well, but if I think about it, I believe I don't. I'm on vacation, so I can't confirm.

My gut tells me it's a bug, because even if the whole being in the narrow wave thing makes sense, at least for me, the thing lasts too long, could go for several seconds or half a minute at times. Normally, it'd only happen once in a while, because the real target (eg. wingman) maneuvers and doesn't keep flying formation with me.

The length of time it lasts for me is consistent with the length of time a SAM or bogey would engage a friendly airplane.

It is a bug. Overall only the spiked aircraft's RWR should make any noise about this. More complex behavior (eg what HB is talking about) is actually more complex and not at all as simple as things are modeled right now.

Then it would be good for the OP to get a track so ED can fix it.

Not completely sure what the geometry of the situation was, but yes it may very well be intended. The RWR has no idea about who’s ‘supposed’ to be locked/targeted. All it knows is that an RF signal is detected with parameters that match a threat signal in its library.

If your RWR is within the beam of the radar, or (depending on range) in a side-lobe, or really any possible position that would allow the light (rf energy is light) to be detected by the RWR receiver, then u will get an RWR indication/spike.

It should also be noted that engineers go to great lengths to make RWRs very sensitive as to inform and protect the pilot. Also, unlike a radar receiver, an RWR receiver only has to deal with one way path loss, making all the better at detecting signals at range.

Again idk if u experienced something different or if there is an actual bug. Just thought it was worth mentioning
