Saab 2000 Airborne Early Warning and Control Aircraft - Air Force Technologywell i have to agrr with this, we never find out that weather the 360 degree coverage is as effective as it is in rest of 300 degree or is it with or without ESM, and if with it how effective is it??
the effeiciency of such platform wont ever surface as they are classified info!
regards!
There are alot of acronyms thrown willy-nilly about. I pointed out a while back on why the claim of 360deg coverage by Saab should be suspicious. In order to understand why it should be suspicious, one must understand basic ESA antenna operation.The system is capable of tracking multiple air and sea target over the horizon and provides above 20km altitude coverage, 360° coverage and has sea surveillance capability.
Main beam dimensions affect cell dimensions. The appropriate analogy is dividing a fixed volume into individual cubes. The goal is to have as small a resolution cell (or cube) as possible in order to distinguish multiple targets. A B-52 will occupy multiple cells, say 100 for example, whereas two small birds inside one of those cells will be seen as one target. But then if a higher freq and/or a larger antenna are used or combination of both, then the two birds will be discriminated, and of course the number of cells that the B-52 occupy will increased, like 100,000 cells, for example.radar resolution cell: The volume of space that is occupied by a radar pulse and that is determined by the pulse duration and the horizontal and vertical beamwidths of the transmitting radar. Note: The radar cannot distinguish between two separate objects that lie within the same resolution cell.
I don't say 360° coverage is not possible, but all sources claims only a max of 300° radar coverage, as I said even the official Saab 2000 Erieye video shows detection only in this area and not in the 30° to front and back. Of course they don't mention it in detail, but there must be a reason don't yo think? The only thing I want to know is how else they achive the missing 60° of coverage (most likely through ESM) and with what performance.i never meant to offened you, sorry if you take it like that,
however it was rather strange that you again claimed that the Erieye will have a 150 degree coverage on both sides, makeing it 300 degree in total and rest of the areas will relay on other sources while the post was clearly claiming that changes have been made to original design to give it 360 degree coverage,,,
however, i agree that it do not have much to do with ones flag but the about the fact that how reliable the soource claiming a point is. in this regard i guess you will agree with the content brought up by various poster clearing the full 360 degree coverage!

The SIGSTAR is a special version of the Saab 2000 only for Siginit and Elinit gathering, not for AEW, both are 2 different aircrafts with differen arrays and antennas. Search in this thread, I posted some pics and infos about them before.I just read on some sites that he Saab 2000 is also positioned to carry signal Surveillance, Targeting, Acquisition and Reconnaissance (SIGSTAR) mission but would PAF version have this capability it is yet to know whereas any advanced AWACS will have it from beginning.
Now if that is true for PAF's version then your argument is pretty valid as it will add a "C" with AEW role of Erieye making it AEW&C. Otherwise this C only came with the help of Ground station which is a major difference between a classic AEW&C and AWACS.
Hope this will explain a little
Me either, the earlier version was the Saab 340 which had also 2 radar arrays with a detection of 120° each, the actual Saab 200 was improved to 150° each.I am not talking about earlier versions i am talking about up to date data which states that Radar provide 360 degree coverage (with or without ESM system).

Thank you for the explaination Gambit! What about ESM and detecting, or tracking aircrafts? Is that possible and in what distance could an aircraft be detected?So in order for the Saab system to increase from 120deg to 150deg would mean either an increase in antenna size or increased freq employed or a delicate combination and balancing of both factors. But because this is still a planar design, it is very difficult to see how the main beam, or lobe, can approach literally 180deg coverage. I am willing to bet that the 360deg coverage claim is more for puclic dissemination than true technical capabilities.
Ok then explain to me please, how will it be modified to achieve the 360° coverage? Will it get 1 top radar array like the Boeing Wegetail? Will it get 2 radar arrays, one on the nose, the other on the back like the Gulfstream Phalcon AWACS?the Erieye PAF is going to get we modified according to PAF wish and now give 360 degree coverage...
now i gusss it is the same thing posted in last 20 or so posts, references provided, explanation give..
still if you think it is 300 degree, you are the einner dude,,, !

There is only this claim of 360° but no real explaination how. The systems I mentioned above shows different ways to achieve that, but as far as I understand it, the Erieye won't get new radar arrays right?
Btw, feel free to disagree! I don't want to convince you, or somebody else. I only want to have a discussion about it and get new, or better infos about the systems. But as far as I only hear it is possible, without saying how, I also feel free to have a different opinion.
I would guess attaching T/R modules in double sided S-shape or I-shape array (instead of straight l-shape array) would achieve 360 degrees.
AOA SIR WHAT IS AWACs/. WHAT I STANDS FOR
That's it mate, provide me an atricle that explains and not only claims how Erieye will achive that coverage and I'll follow your opinion.i am not objecting to difference in opinion. I am no one to object as this is a public forum and all of us have equal rights here,,,
the thing that i am concerned is that despite of being provided various articeles claiming 360 degree coverage you seem to stick to the idea. i am not an aeronauticle engineer who can explian how, all i can do is to provide you with articles my professionals that this is what it is , , , and i guess you have been through some good literature by now,
anyways dude it is your point of view and have every right to carry on with it, i cannot object. however i will always try to convince other members about my point with those articles as i take it as my right to avoid them to be misleaded!
discsussion with some costructive ambitions is always welcomed!
