Mig-21bis NEEDS a lower BR

By PRF.

How can PRF be outside SPO10’s range, when it’s several orders of magnitude lower than radar frequency?
SPO10 is a rather primitive device with little, if any filters, so it’s gonna pick up pretty much anything within and on the fringes of its op.freq.band and just toss it at the pilot in the cockpit, to figure out what’s what.

I know, but dunno much about it.

Due to the second pulse either, occurring outside the reference frame if the rate is too low, or an inability to sample the returns sufficiently to make a determination due to bleeding into adjacent sample timesteps if the rate is too high (and further reducing the effective Duty cycle and and so reduce the apparent received energy) and so cause issues with signal detection and classification.

It doesn’t matter how analog or digital the system is, it is still composed of tuned circuits and so has to chose between resolution or a wide spectrum, and since there are limits imposed on the resolution for workable classification of the signals, the width of the received spectrum is thus also limited.

Yeah, ok, but we’re talking about CW here.
It’s most likely the highest PRF allowed by a carrier frequency, so it’s well within SPO’s range.
I mean, what’s the point of a CW if it’s PRF is below H band? The resolution becomes way too low for the AAM guidance.

That makes no sense, PRF is used by pulse systems to demine the maximum unambiguous range / range rate that a target can have before it becomes ambiguous (e.g. second time around returns) or gets lost in clutter (staggering the pulses or interleaving has a number of tradeoffs).

The issues with a low PRF becomes one of polling, where target returns are not gathered often enough to be sufficiently useful, Where High PRF’s have issues with low efficiency (power) and range.

A continuous wave cannot have a PRF, it is in the name; the signal is either Continuous or pulsed not both, CW is effectively a special case where the waveform has an 100% duty cycle / pulse width (the same way a square is a special form of rectangle), so with a single transceiver element there is no time left to listen for the returns in any given cycle.

Ok, we getting sidetracked here…of course the CW has PRF, it’s just 100% of what TWT is giving out, as you correctly concluded later, in your own words…and radar in CW mode doesn’t listen, SARH missile does.

Anyway, this is the theoretical background behind SPO10’s practical ability to pickup search, TWS, STT, or CW signals in its operating bandwidth.

It doesn’t matter if it can or can’t pickup CW / Tracking emissions since it can’t differentiate between the two, which is why it doesn’t have a separate dedicated launch warning, since detecting a Track or Launch signal would need to be respected and conservatively interpreted as a launch warning to avoid issues.

This was an issue with the F-15 (PDI Sparrow / AMRAAM guidance) / Tornado for a period of time.

Also the fact that auxiliary Sparrow launch methodologies that did not rely upon the radar for Antenna training Error correction are not (yet) implemented, makes the point almost entirely moot in effect due to most aircraft lacking sensors or the ability to independently employ them and as such a radar track must precede launch, even though this was not true in many cases.

e.g. F-14 via IR / EO / IIR sensor(s)

Well, it DOES matter since neither track, or CW are available in game and they should be.
That’s the point of this whole discussion. Also, SPO10 doesn’t recognize launching sequence, but a skilled pilot can figure it out, on his own, since the RWR has next to none filters.

I don’t think they are ever going to add an aural channel to RWRs since that’s towing the line on accurate portrayal of tactics, let alone modeling it for modern, or current systems across the threat spectrum, that would need far more technical information, let alone each specific system’s modes of operation.

Yeah, but it’s not that important after all.
However, SPO10 should really get back its fundamental use, since, as it is, Bis is rather useless in Sim Air, particularly in EC.

PRF does not equate to carrier frequency. Whether it’s LPRF, MPRF, or HPRF, the CF will always remain within the same band unless its a radar capable of changing it (phased array radars, primarily).

HPRF frequencies are hundreds of times lesser than the lowest rung of any carrier frequency.

CW is ingame btw

In CW it does, but I see GJ struggling with that too.
Can’t find APA-127/8 frequency, but it must be within the X/Ku band, for the resolution.

Who would’ve thought that my (correct) rant about the mig21 would get so many idiots to comment here. Yes the mig21bis is shit. No, none of your arguments otherwise are valid. The thing needs to be 10.7, or every single jet at 11.3 and up needs an increase in BR.

lol are you just baiting or what, cause its a good bait if so

This thread is something else.

Dude really thinks the Mig-21BIS is suffering where it’s at, which is a fair assessment. However, there are other aircraft that are suffering even more at the same BR.

What is needed isn’t it being downtiered - If anything it needs to be uptiered - Same with other platforms that are running All-aspects so that they are well away from facing aircraft that lack countermeasures. However, such a thing needs to happen with BR decompression, meaning we need higher BR ratings for the 11.0-12.7 aircraft so that they can also be adjusted accordingly because as we all know the entire aircraft BR range from 8.0 to 12.7 is compressed to hell and basically nobody has been having a good time for years.

your memeing at this point right? the f14a has aim9h’s. The phoenixes arent even 20g, and the 7s are 25g. The russians have a better starting missile for things that the 11.0

He’s likely rating it that based on the airframe and it having a good radar+SARH missile to use with it, as well as the actually pretty decent phoenixes

“No arguments are valid because i said so.”

With such ego, I bet you browse a reddit for at least 8 hours a day.

As if this forum is better lol

Mig21 needs real life SPO10, as this one makes plane useless.
F14s, F4s, Mig23s, whatever has a MRAAM render Mig21 unusable.
F4F eg. doesn’t have all aspect AAMs, but it’s RWR enables it to survive 11.3 BR eg.
SPO10 doesn’t enable Mig21 to survive in BR 11.3.
This is why you don’t see Mig21 in EC.

GJ’s decisions in “balancing” the game are really beyond comprehension.
On one hand they give Soviet WW2 planes fantasy properties, but then the Mig21 (probably most popular Soviet fighter ever), doesn’t even get RL characteristics. Go figure…
