Since there's been so much talk of late about Iranian developed Radar Systems, I think we should have a dedicated thread to the topic. There are many images of Iranian developed radar systems but little background on them..Some appear based on foreign systems while others look very unique.

Eagle, Is there any low powered radar in the world that is build with low powered solid state technology and does not look like these monsters?

Eagle2009 · « **Reply #2 on:** July 07, 2010, 05:05:18 AM »

Thats a very good question lol..I am really just an amateur when it comes to understanding Radar Technology (I understand the basics but AESA/PESA systems are a bit confusing). However, Long Range systems traditionally need a pretty decent sized antenna because having a smaller antenna actualy limits the scope the radar emissions and would logically weaken its range. The other problem is, radars take alot of energy so a low-power system is therefore likely to be rather short ranged, but overtime Radars have gotten smaller and smaller thanks to more advanced electronics so logically its only a matter of time that longer range radars require smaller antennas.

Here are a couple of great links for Russian and Chinese radar systems which we can look towards for comparision to Iran's systems. This site also have several impressive studies/reports on Anti-Stealth Radar systems, Long Range systems, and a very impressive collection of info on Russian and Chinese SAMS (and their associated radar systems).

Here is an interesting comparision..

Notice the similarities with the afore mentioned "INR-1" and the Chinese YLC-4 Long Range Radar system. The YLC-4 is a 2D Early Warning Radar system (designed for both Military and Civilian use) and uses modern solid state electronics and has rather impressive range (up to 410km). Now, thanks to the poor quality of the image of this INR-1, we can't be certain whether it is actually a imported Chinese system or an Iranian-built model, but regardless it is a very good radar system to have.

Does anyone have photos/information on the Basir-110 radar system? I know there is a D and S variant, and that it may be based on France's Rasit but I tried looking it up on the IEI's website it denied me access (no clue why)..Very much appreciated in advance!

I've been getting the same "denied access" thing as well, my guess is that since this is a new site, they still haven't gotten the kinks ironed out of it, because at least some portions of the site work.

As to the Basir 110

110-S
-Manportable, 25 kg
-solid state digital electronics
-self contained power-supplt
-GPS reciever
-Operates in the Ku band
-Detection range: man-sized:2.8 km, light vehicle:5 km, heavy vehicle: 6.5 km
-track while scan mode
-mounted on a tripod, vehicle, or mast

110-D
-Similar to 110-S
-X band
-Dectection range: Man size: 18 km, Light/heavy vehicle/helicopter: 40 km
Accuracy:<10 m

Picture: 110-S

nice thread! been reading and its interesting.....

Eagle2009 · « **Reply #7 on:** July 07, 2010, 03:36:00 PM »

Much Appreciated Ayyash for the pics/info.

Most of the pictures come from ACIG, including their non-official designation of "INR" (Iranian National Radar). However there just isnt alot of information on them and in the case of the other two (INR-3/4) we're not even sure of their size. The INR-3 was described by Tom Cooper as being generally similar to the Chinese YLC-6, though to me they seem quite different in appearance but more interestingly, another Iranian Radar also looks generally similar to the YLC-6 but doesnt much look like the INR-3...All quite confusing lol. See below.

A great video! At the 3:58 and 7:22 we can see a radar previously unseen to me..and its looks very much like the Chinese YLC-6! Both in its very structure and the antenna's overall shape. While its hard to be absolutely certain, I'd say this the best evidence yet of Iran producing its own version of the YLC-6.

Lur · « **Reply #12 on:** July 08, 2010, 11:23:37 PM »

is the YLC 6 modern?

Eagle2009 · « **Reply #13 on:** July 08, 2010, 11:43:43 PM »

As a Medium Range Air Search radar system, yes. Its a 2D system, made with solid-state technology. Its claimed by the Chinese to have excellent ECM/ECCM resistance. Apparently the Chinese have deployed large numbers of these fairly cheap and mobile radar systems along their coast facing Taiwan.

Specs of the YLC-6:
Max Range- 150km (against a 2meters squared RCS target)
Max Altitude- 10,000meters
Set Up Time- 8 mins
Withdrawal Time- 6 mins

Well the good people at the ACIG have set me straight about the Radar system I pointed out in the video. They do confirm Iran is working on YLC-6 based radars but the particular radar I noticed isnt it..But its not bad news believe me! After some indepedent research of my own, this radar is actually an Iranian built version of the American TPS-43 radar. This radar was first produced by the US in the late 60's and is a 3D road mobile radar system. The really impressive thing is the range of this radar, 300-450km! While a bit of a dated design, for its time it had great ground clutter and ECM/ECCM resistance. Furthermore its entirely possible that Iran has added more modern digital and solid-state elements to this radar to improves it overall performance and resistance to countermeasures. Overall, its a good radar with great potential in Iran's armed forces (for example perhaps fitted on future large naval surface combatants?).

No idea, but it's newly accessible on the new IEI website.

This radar, BSR-1 is like the VHF radar recently shown off this year's little brother. The larger radar shown off earlier this year (image below) is clearly a much larger system akin to the Spoon Rest radar but with solid-state technology added and more mobile. The BSR-1 seems to be a more compact/simplified version of that radar. If the Spoon Rest is any indication, this radar could detect small RCS targets but likely at very short ranges. Updated versions of the older Spoon Rest VHF radar can detech an F-35 sized target up to 35km away. This smaller radar likely could detect a similar sized target maybe 10-15km in my opinion but I am just going by what its range is compared to larger radars. However it could be very useful against targets like cruisemissiles which generally have a RCS of 0.1 meters. Considering how much smaller and likely cheaper this radar is, its usefullness is pretty good for its size in my opinion.

EDIT- Upon reading the brochure more carefully I am a little puzzled. I actually states the minimum RCS for a target is 1meter squared. Most cruise missiles today are closer to 0.1 meters..Perhaps a little understatement in the brochure?

Eagle2009 · « **Reply #20 on:** August 27, 2010, 05:53:58 AM »

The TM-ASR-1 seems fairly similar to the Chinese YLC-6 in terms of range but this radar operates on a different band (S-band unlike E/F band of the Chinese radar) and has a greater detection height of 14km instead of 10km with the YLC-6. A very interesting radar indeed!

By the way, Great Find Ayyash!

I think this is a very cheap radar to be produced in hundreds and maybe thousands to protect against cruse missiles.

The 1 m^2 RCS is for 120 km range and at closer ranges say 30 km, it might be able to detect objects with very little RCS.

Simple math 120/30 = 4 => 4X4= 16. 1/16 = 0.06 square meter which is the size on an Eagle, lol.

Eagle2009 · « **Reply #22 on:** August 27, 2010, 06:30:48 AM »

But we dont know if the 120km if for a 1m squared target. The page actually simply states 'Minimum RCS-1meter squared' which could either mean it can detect such target 120km away or that is the smallest target it can accurately track. The fact they mention the max range several times I think that later is more likely.

Also I'm not sure about your math..but I dont think its correct. Calculating RCS ranges for radar isnt that simple or even. For example, the NEBO SVU can detect a 1meter squared target at a range of 277km. It can detect a 0.1m squared target 166km away. For a 0.01m squared target, the range is 92km. That means that the range changes by 40% from a 1meter target to a 0.1 target. It changes by 44% when going from a 0.1 target to a 0.01 sized target (it changes much more so when detecting smaller targets). So assuming (and this is big assumption) this radar's range reducing in a similar manner, its range against a 0.1 meter target could be 72km. Against a 0.01 target the possible range could be 40km. This all assumes two things, that is radar's stated range is against a 1 meter target and that this radar is close to as advanced as the NEBO for the scale to be even remotely accurate. Considering the antennas looks much simplier than the NEBOs I suspect that later assumption isnt a good one.

Eagle, my calculation is a very underestimation of the radar capabilities since it is only reflecting the exponential increase of electromagnetic waves strength by closer distance and does not take into consideration the geometry which in best case scenario gives it 16X16 resolution resulting in RCS of 1/256= 0.004.

which is smaller than the size of an Eagle wing.

I think 1 m is for 120 km that's how people do specifications other wise none of the 120 km and 1 m numbers have any meaning.
