Did you put that mark or was it really there?


No I mean:
فارسی را پاس بداریم چی شد؟

no i did not put it there.

خب پاس میداریم من که مخالفتی ندارم ولی بلاخره انگلیسی هم زبانیه که اینجا و توی اکثر دنیا به کار میره و منم مشکلی با استفاده فارسی یا انگلیسی ندارم ولی ترجیح میدم انگلیسی بنویسم چون اینجا اکثرا انگیسی صحبت میکنن و قدرت نظامی ایران هم بهتر به بقیه معرفی میشه اگر بخواهم فارسی بنویسم مجبورم برای همه ترجمش کنم وقت این کارو هم ندارم ولی اگر کسی متوجه نشد یا به فارسی هم مشخصات یک سیستم رو خواست من براش میزارم.

Today Channel Ofogh
13:29 "War of waves" part 3

there was no part 2 or 3, it was the rerun of the first one.

 

[skyshadow]

Sayyad_2 or Talash_2 with Najm_802 B radar that can engaging 6 targets simultaneously.

Sayyad_3 system with Sayyad_3C missiles and Ofoq radar

 

[skyshadow]

Najm_802 B radar that can engaging 6 targets simultaneously

 

[Mithridates]

so sayyad-3 weights almost one ton.

 

[skyshadow]

so sayyad-3 weights almost one ton.

yes its more then one ton 1023 kg

@PeeD can you say what are your thoughts about Arash radar? in the photo they have put it on top of a building in middle of the city.

 

[WinterNights]

It looks like an L-band long range radar.

 

[mohsen]

Yeah, but on the EPG it was described as part three!

Ghadir_2 OTH radar

range: up to 3000 KM

Where did this 3000km come from?

 

[skyshadow]

Yeah, but on the EPG it was described as part three!


Where did this 3000km come from?

they said 3000 km for Ghadir_1 already and if Ghadir_2 is as big as 1 then the numbers will match but if not then it will be between 1000 to 2000 km

 

[mohsen]

they said 3000 km for Ghadir_1 already and if Ghadir_2 is as big as 1 then the numbers will match but if not then it will be between 1000 to 2000 km

No they said the range of Ghadir is 600km for aircrafts and 1100km for ballistic missiles!

 

[skyshadow]

No they said the range of Ghadir is 600km for aircrafts and 1100km for ballistic missiles!

you are right it was Sepehr radar with 3000 km range

رادار سپهر که به عنوان دوربردترین رادار کشور نیز مطرح می‌شود از نوع رادارهای ماوراء افق بوده و به گفته مسئولین دفاعی برد معمول آن 2500 کیلومتر است که قابلیت تغییر از 800 کیلومتر تا 3000 کیلومتر را نیز دارد.

نه منظورم سیستمهای کنترل رادار و موشکی ایرانه. همه ابزارآلات به انگلیسین

Right, so it's cost effective. But how is it more capable than the S-400?

You mean the Bavar-373 or just the Meraj-4? The S-400 is a brute force system, very mature and with significant ABM capabilities. Bavar-373 uses newer technology solutions such as all-AESA radars. Will it become better than the S-400 by this? Can't say for now.
If you mean Meraj-4 vs. Big bird: The job of both systems is long range 3D volume search. Here a PESA is equal to an AESA. The AESA is just more reliable and has lower noise = longer range if both power outputs are the same. So if the radar does not work 24/7 and has higher power output it is as good as the AESA in this application. These radars are not beam forming and doing special tasks like Irans S-band AESAs, just search at long range to detect early and pass information on to acquisition-level systems.
It seems that Iran reached similar range performance as the Big Bird with the Meraj-4. The statement of 200 tracked targets underlines this: This is Bavar-373 division/battalion level battle management radar and tracks more targets than the (at least export) Big Bird.

@PeeD can you say what are your thoughts about Arash radar? in the photo they have put it on top of a building in middle of the city.

It looks like a upper L-band or lower S-band PESA. Its a IRIADF volume search EW system with large array and hence range performance. Related to the Moghareb.

Baradaran at military.ir have found a recent study which analyses radar absorbing structure very similar to that visible from the RQ-4 wreckage.

They also found a crude, undetailed shape RCS analysis on the RQ-4.

Shaping accounts for ~ 10dB in that crude analysis. We can assume a magnitude better performance if the model had higher definition shaping, hence 0 dB. Shaping is obviously not the greatest stealth technique the RQ-4 uses.

However its double layered honeycomb composite sandwich structure, RAS has a surprisingly high performance. -25dB in 3rd Khordads X-band. We can add another -5dB assuming optimized details beyond the capabilities of the study.

The results are a stealth performance of -15 to -30db.

This performances would create serious problems for the 3rd Khordad at the stated interception range of 22km. -15dB would be already the edge if we assume very good GaA TRM technology.
-30dB could not be handled even with best available GaN TRMs...

Either the RQ-4 is not the absorption black hole these studies hint to, or the 3rd Khordad is either somehow high performing or skips to brute force X-band vs. high performance RAS approach by using a different approach (like thermal camera guidance).



Another issue: It is possible that the RQ-4 was minimally violating Irans airspace regularly and was painted/locked by 3rd Khordads as a warning but never shot at. This would create a false sense of security and if no sensor detected the 3rd Khordad launch, it would become a ambush in which it would be suddenly hit by missile.
