Tech nerd question: how does the RWR generate sounds IRL?
-
As the title says, in the real jet, not in BMS. Is it an electronic sound generated by the system or does it convert the received radar signal into sound?

It depends on the RWR model.
But basically for most of the F-16:
_"Audio Tones.
New threat audio for an airborne radar is two repetitions of a chirped (25ms on/off) 3000 Hz tone generated for 400 ms followed by a 400 ms quiet period.New threat audio for a surface radar is two repetitions of a chirped (25ms on/off) 500 Hz tone generated for 400 ms followed by a 400 ms quiet period.
When an ambiguity between a surface or airborne radar is detected, the 3000 Hz tone is generated.
Missile launch audio is a 1000 Hz tone, on for 100 milliseconds and off for 100 milliseconds, generated for 2.0 seconds. This audio sequence is equivalent to approximately seven beeps. The missile launch audio is recycled every 15 seconds for as long as the detected emitter remains in the missile launch mode. The missile launch recycle audio is a 515 Hz tone, on for 100 milliseconds and off for 100 milliseconds, generated for 2.0 seconds.
In any hand-off mode the audio heard is equal to the PRF of the emitter; however, this audio is clamped to 3000 Hz for an airborne emitter and 500 Hz for a surface emitter. To indicate that the airborne emitter audio is clamped, the 3000 Hz audio is chirped at 75 ms on/1411 ms off. To indicate that the surface emitter audio is clamped, the 500 Hz audio is chirped at 48 ms on/752 ms off. Emitter audio is terminated when the emitter loses track.Failure audio is a 300 Hz tone with a duration of 2 seconds."_
In Falcon, PFR can’t be dynamic so it is a generic sample is created for each radar mimic in a consistent way a given radar but won’t changes depending on PRF variations.
It can’t be 100% realistic since what you hear IRL is the PRF converted in an audible frequency. IRL, for a same radar, it can take a various of forms.Here is several audio samples to compare what it might sounds IRL vs BMS tones : https://www.dropbox.com/s/j7lkmsopskhiktz/RWR%20sounds%20alanayse.rar?dl=0
