Do you have any info on what this homemade airborne radar is.
Thanks
From what I have read, there are two homegrown radars in IRIAF currently being used
(1) SAIRAN Bayyenat-II on Kowsar-I which is an exact replica of Leonardo Grifo-346. Count the T/R modules, and arrays and see the oscillator and processing units. It is a ditto system. It is the most modern radar in the Grifo series except for their Grifo-E AESA. It has an ECM, look-down shoot-down, and high-resolution SAR (better than IRBIS E of SU-35S). The Max tracking range is 94 KM for a 1 m2 target while search range is well into 120 KM enevelope. The radar was shown at Kish airshow and then again at Kowsar's unveiling.
My own take (Assumption): It is a TOT from Chinese CATIC who got Italian Grifo radars secretly through an under-the-table deal for developing their own local NRIET KLJ series for their light fighters such as KLJ-6E for J-7E/BG series, KLJ-7 for FC-1/JF-17, and KLJ-7A AESA. We know CATIC was in Iran for years working on Azarakhsh and they installed Sy-80 FCR of J-7N on Azaraksh. For project Silk Route-II, it is quite possible that TOT of a modern Chinese replica of Grifo-346 landed in Iran. I would have a hard time believing Italians will give something to Iran directly and get away with it right under NATO's nose.

The capabilities (taken from Grifo's brochure) are written on the left side.

(1) SAIRAN Bayyenat-I on Dowran F-4E/D. Pulse Doppler FCR with 100+ KM tracking range for surface-bound targets atleast. It can track maritime targets at long range for Ghader/Nasr AShCM. The foreign origin seems to be missing, could very well be an indigenous design based on blue prints of APQ-120???
They are OK systems for the start. IRIAF needs local AESA with a track range into 140+ KM zone for long-range BVR attack. That is where the world in moving. These pulse doppler radars were good in 2000s but not anymore
