president Rouhani inspected Shiraz Electronic Industries

[IranDefence]

- One new AESA radar, an evolution of Hefez and Bavar accusation radar, with close to twice the emitting power of the Hafez
- The production variant of the SAR for drones
- Iranian Skyguard copy
- T/R modules for AESAs, some of which look like lastest on-chip GaN X-band modules for Bavar engagement radar

Quite important things where shown there.

Can you give more details and highlight the modules in the picture?

Huge if this is the case!

Navid firefinder radar

The Navid fire-finder radar has for some reason a secondary array on top. This would make sense for a air defense radar (IFF) but not for the artillery fire-finding radar.
Its also a quite powerful and large AESA for fire-finding purpose. Maybe its multirole with secondary air defense capability.
I recommend air lifting 2-3 of these to Syria together with GPS guided Fajr-5Cs. It would be the ideal enemy artillery killer.

@AmirPatriot

I was talking about the items on the table in photo #2 you posted.

Thanks. Which specific items, and why do they look like GaN modules?

 

[Fafnir]

The radar in the middle looks like something new that we havent seen before,it looks a little like a spoon rest but has 12 yagi antenna rather than 16,another vhf radar for detecting lo/vlo stealth targets perhaps?

That's Matla'ul Fajr 1. It has been around for quite a while. http://www.mindexcenter.ir/product/semi-long-vhf-air-surveillance-radar

Well, they look like GaNs because T/R-modules seem to be displayed on that part of the table. Conventional stripe like modules likely for X-band and likely GaA. Further down the table several single chip items are shown. Because the power density for such small on chip modules would likely be to high for GaA modules, to me it looks like those are X-band on chip GaN modules.

But we can't know at the moment, maybe Shiraz electronic industry also builds some CPUs and that what is shown below the conventional TRMs. The conventional module is also new. Previously the IRGC has shown the assembly of S-band TRMs for Najm 802 but this is the first time we see X-band TRMs (either for 3rd Khordad, Bavar engagement radar, or even Talash-3 engagement radar).

If they managed to build on chip GaN X-band modules, we can expect the Bavar engagement radar to have them and this being the reason for its relatively small array size compared to S-300/400. It might even have a 3D-array for improved beam steering characteristics.

So much for what it looks like. But because its microelectronics it could be something completely different.

Thanks again PeeD.

I got some higher resolution pictures from president.ir

Sorry if I am being pedantic or I can't know your meaning, I am not familiar with these very technical aspects of radar design. Which are the specific modules you are talking about? I am assuming it is the ones in the green circle. The ones in the black circle look like CPUs to me.

By the way, your technical contribution to this forum is highly appreciated bro. Please, if you are active on any other sites or forums like Twitter, let me know.

You'r welcome Amir, I keep it here, since IMF is gone. But I don't talk too open, too many eyes watching here, e.g I would not post such high-res photos for potential opsec reasons.

The modules in the plastic boxes next to the blue circle should be GaA X-band modules. The ones in the red circle are candidates for X-band GaNs. At least it makes no sense for Shiraz electronic industries to produce other chips than TRMs, they would buy things like CPUs from outside sources, not produce them as displayed by those chips.
However I'm no microelectronic guy.

Great strides Iran is making on its own in electronic warfare systems. all the best......way to go

Well, they are published by the official website of the president, so I think the Persian cat is already out of the bag...

Hmm... maybe I should ask around if there is someone on the forum.

The Navid radar should be very similar to this Israeli radar EL/M-2084:

It should be a multirole radar, a counter battery radar and a air defense radar. Both are S-band AESAs but due to the experience of Israelis with AESAs, the EL/M-2084 should be more powerful.
