RWR measure received EM wave characteristics. This provide means for accurate direction finding , via phase interferometry notably, said to be less 1 deg even for most basic settings , but also range by measuring doppler change rate (precision unknown and depending on target change of attitude). Any how sets of measures will ultimately provide good localization over short time, especially since other more basic methods and measurements ,still based on Doppler, can confirm the measurements.
.
dont you mean kinematic ranging ?, that kinda require target to remain a constant course for location estimate
Bad? No, it comes down to choices. LO design choices dictate a fixed array angled as to not reflect, and the cost of 120* max FoV without additional arrays. A repositioner obviously adds FoV, at the cost of added complexity, reduced space, possible RCS increase.
Agree, all design is a matter of compromise
The whole discussion started with the premise that a swashplate allowed the shooter to keep array on the target while turning away. The ability to provide mid course guidance via missile handoff or systems like the AN/ALR-94 provide alternatives.
Iam aware that there alternative , but i think that there are situation where a RWR cant replace swash plate radar .For example: if both side turn aways after launching their missiles.
Well, if it was that simple they wouldn’t have built the F-22 this way. Supercruising reduces the IR sig a lot and also gives the plane a much longer supersonic range.
Supercruise doesnot reduce Infrared signature , you cannot go faster then expect aerodynamic heating not increase your airframe temperature. As soon as you go mach 1.7 , supercruise or not , IRST gonna detect you from afar
In other words, the F-22s should be phased out and replaced by the F-35, you say.. If they are inferior in their primary (and pretty much only) role than the aircraft they are supposed to protect, this all at double operating cost, then there is basically no reason to keep them operational..
They not inferior per say , superior speed mean they are more useful in interception role for example. It just that when stealth aircraft face off against each others , then speed could be counter benefit.
I’m sorry I fail to see why you are posting this. No one is arguing which provides superior targeting data, it would obviously be radar.
The question predicated on the ability of these systems to provide data for mid course updates.
My point is that while RWR can be substitute for radar to some extent in mid course guide , i dont think swash plate is a bad decision , it fact , i think it quite interesting one
I am, like Wilhelm, sick of being lied to by politicians and being spun a line by those prosecuting an illegal and secret war without parliamentary authority against a sovereign nation, Syria, and a war designed illegally to topple Bashar Assad. Why are we fighting ISIS in London and Paris and New York, but in Syria, not only are we turning a blind eye to ISIS, but we are aiding and abetting the “moderate” terrorists ISIS and whatever new name Nusra have changed to today (same lot and the whole world knows it) to overthrow the secular government of Bashar Assad who are fighting ISIS and the Jihadists?
They do not intentionally aid the ISIS though , and the “moderate” group that fighting Assad regiem isnt in the same group as ISIS, moreover , you also get group like hezbollah that actually in the side of Assad regiem. And where is the evidence that US ignored ISIS in Syria ?? , they still bomb and attack ISIS group everyday
Garry, welcome to the decadent West 😉 Just like your chum mig-31b (another LM bot….is he on holiday or has he found a real job?) we all know which side you’re batting both for 😉 I hope you do well and make good here in the sleazy west (joke) while also making a few dollars….I know we all have to pay our bills somehow, but the reason you’ve gone on and on about the night fighting capabilities of Syrian is helicopters because you repeatedly and in every post keep trying sneakily to connect the Syrians or Russians to the attack on the aid convoy without any incontrovertible evidence whatsoever (you should give back the money for a sloppy job (joke), while at the same time talking about bias in other people 😀
Show me real evidence and not a Bellingcat or AgitPapa type analysis, which as Marcellos says, both are plausible, but not conclusively believable and then we’ve got something to talk about….but until then no one really knows what happened ….. all except the “moderate” terrorists who were in control of the area where the aid convoy was because they were there and if they are anything like the white helmet members who took a selfie of with Syrian prisoners before killing them and like the daft people they are uploaded the photos and video for the whole world to see https://twitter.com/agitpapa, and now we can all see that the white helmets are not in fact the Red Cross but really in fact many are provable “moderate” terrorists.
So it is fine for you to have opinion that support Russian and Assad , but if anyone have opinion support US or Western side then they are a shill ? really? what kind of stupid logic is that ? or do i have to sneaky link jihadists and American in every post like you ?
It said at the start that the attack could be done by Russian or Syria , and Crow said Syria airforce dont have night fighting capabilities , that why i asked about thermal system on their helicopter , what wrong in that ? or i have to blindly accept whatever given without asking any question ?
You now acknowledge at last that the SyAF operates antique early models of helicopters and planes without sophisticated or even primitive night-fighting capabilities, so tell me how the white helmet members (aligned with jihadists and sponsored by America and nothing to do with the Syrian Red Crescent or official Red Cross) who happened conveniently to be there to give a running commentary on the aid convoy being attacked) were able to see barrel bombs (favourite code words in every script against the Assad regime 😉 in the night in pitch darkness? With no lights how could they see? And how did they even see the helicopters assuming they were without lights and not lit up like a Christmas tree were but were in pitch darkness?
Also what were the jihadists doing towing the heavy mortar doing weaving in and out of the aid convoy?
Why did the Jihadist towing mortar along side the convoy ? may be they hoped that they will not be attacked because either Russian ,US have to care about colletaral damage , arent they doing that all the time ?
There are 4 situation that could have happend:
Case 1: Syria did it , and the moderate saw their heli , that could be explained that the Syrian installed some extra night vision system on their heli or let pilots use some night vision google ( not in a proffesional ways but more in line of temporary solution ) then the moderate may saw their heli either because of the collision light system or because the aircraft use it’s cannon as well
Case 2: Russian did it with their Su-24 , no one see anything but because it is a dive bombing , people can hear jet noise and the unguide bomb of Russian kinda look like the barrel bombs of Syrian regime
Case 3: IED and everyside want to blame someone
Case 4: Attack was done by US with their Predator
Also, if it were not Syrian helicopters and instead two Russian Su-24s, why wasn’t the sh!t kicked out of the convoy after a few tons of bombs were dropped? You’ve seen the video just above posted by Crow11 to see the aftermath of a real Russian bombing attack and it bears little resemblance to the photos after the attack on the aid convoy ….see more photos of lorries after attack here https://twitter.com/agitpapa.
For argument’s sake let’s say the Russians and Syrians did attack the aid convoy which was in an area under the control of the “moderate” terrorists, then why attack this particular aid convoy when one hadn’t been attacked before? Seems a bit fishy…..and something does not seem right…..; -)
Not all bomb after match look the same , it depending on the kind of bomb you used and how many of them you used too, Why that particular convoy was attacked ? could be simple case of target of oppotunities more than anything else
A radar can weight as much as 500kg. By removing this, you create a shift in the CG of any jet, which in turn decrease the performance of the jet. So why would the Knights fly in any Flanker that has its performance(controlability) reduced in the first place?
To be fair though, shifting CG toward the rear is probably a good thing in most case
That F 14 pic does not show the profile.
Neither is the PAK-FA pic
Whatever. People say it is accurate but who knows.
It doesn’t take very many pictures of both jets for me personally to conclude that the Pak Fa is a lower profile than the F 35. But I will get to the bottom of it.
f-14 can look flat too ,that picture doesnt show anything relevance really
The F 35 has the same frontal profile as the Raptor. And the Pak Fa has a lower profile than the Raptor.

If your cutaway was accurate then PAK-FA radar would be far smaller than the one F-22, but too bad it isnt accurate at all

RT content on Youtube has generated over 3 times as many views as CNN & Euronews respectively, and 2.5 times Al Jazeera’s viewership. over 540 million views were generated by the network to date in 2014.
Iam not sure if those number are correct or not , and to be honest i cant be bothered to check , but TBH , i dont see anywhere in that link mentioned that CNN admits anything, moreover, it pretty much naive to assume that a new channels doesnt have propaganda or is reliable just because it has a lot of views
‘
We have garryA going on and on about Syrian helicopters operating in the dark when he knows the early models operated by the SyAF do not have night fighting capability
Again , i didnt know that early Russian heli and Mig-29 doesnt have night vision or thermal system , simply assumed that they did have those basic stuff , that why i ask people who know more about those system such as stealthflanker , but i never said it is 100% done by the Syrian force , i simply cast doubt on things i heard unlike some members who readily swallowing any negative story about the West.
The Pak Fa is only longer because it is a full size fighter. The F 35 is a 2nd tier class of fighter.
I dont care which class you think they belong to, but regardless PAK-FA doesn’t have smaller profile
Again, we were discussing mid-course updates. .
Yes iam aware that we are discussing mid course update , but between a system that provide bearing and another one that can provide bearing , distance , velocity then it hard to deny that the later one is superior.
Even so, the Pak Fa has a lower profile than the F 35. Even to the naked eye. The Pak Fa just looks flat. The F 35 just doesn’t.
PAK-FA doesnt have a lower profiles , it is simply alot longer than F-35

Whatever people feel about Sweetman, he was not writing op-ed. He was describing the simulated engagement the L-M engineers allowed him to see. Not to mention that the Journal of Electronic Defense isn’t exactly “Popular Mechanics”. As c

Its a real number. CNN admitted it.
What number? and CNN admitted what? can you give some sources to illustrate your point?
RT is the most viewed international news channel on Youtube by a large margin.
Iam not sure about the number but TBH, i think any smart person would take information from Sputnik, RT or Fox news with load of salt, just a bunch of propaganda channels really.
It rather laughable naive to believe that good and bad in reality is as clear as black and white
