No. Uttam mk1 is better than this. Uttam use diapole arrays which are far better compare to the patch or circular loop(Zhuk AE of Mig35).

Uttam's printed Diapole BTW

Sorry got confused and wrote wrong info

Seems like we're good in radars
With mk2 uttam getting ready
I think we would be at par with western counterparts

Sukhoi Su 30MKI

IAF Su-30MKI is now integrated with indigenously developed winged glide bomb Garuthma. With 100 km range now Su-30MKI can engage ground targets at a stand-off distance

And below research paper too , it's DRDO funded research for ultra wide band application , expect performance better than spectra

Some research by iitk on Vivaldi performance enhancement using metamaterial

 

[Lonewolf]

We are getting very on the hardware side but don't know what is our capabilities in algorithm side. There's still a wide gap between us and the top of the line western radar and with the induction of Uttam mk2(GaN based vivaldi) in our airforce the gap will get narrower. The funny thing is Russia being the guy having one of the most experience in developing airborne x band radar is still very much behind the US/France/Italy and even china. Russia's algorithm side is very strong whereas their hardware sude is shit. Their 5th gen Su57 still uses slot antenna arrays whereas US have moved on with Ultra wideband arrays. Also their claims of Bars and Ibris detecting targets beyond 350km is shit

Let me give a example , remember green pine radar , we upgraded it's range over vanilla mod through software upgrade only , for first upgrade .

Later hardware upgrade were done too . And our Anuradha (desi arudhra ) have been a technical experience of drdo for development of software , they played a lot with main and side lobes in its development .

As far as ik
Our algorithm capabilities are decent

If our Bor conical Vivaldi frutify early we may see it in amca

is there any diff bw bor conical vivaldi and vivaldi ? or are they same ?

which one is in uttam mk2 ?

Our is TSA vivaldi , BOR Vivaldi is a different thing , provide better bandwidth than normal tsa

 

[fire starter]

AI/ML Based Real time Data Analysis System for ESM.

so basically AI will be used in RWR/ELINT for enhancing their performance.

A force multiplier indeed.

I think BOR vivaldi is in same class of f22 and f35's ultra wideband arrays. This things can do the offensive jamming for you, don't need an extra jammer. Top class technology, i hope DRDO find a success in them. We desparately need this exact technology in AMCA

 

[ezsasa]

Guys I was thinking that if SANT 10km range was made for anti armour roles for Helis in all weather roles where iir seeker might not perform that good. Then how the hell does our current Helis locate their target first with their EO pod in such conditions, clearly we don't have MMW radar on them. So either we will see MMW radar on Helis in future and if not I don't really see the need of SANT orders by armed forces as simple Helinas will do the same job.
Also current Helinas are only LOBL as shown in brochures. LOAL capability will further enhance the range of current Helinas as current iir seeker can see up to 7-8km only

perhaps EO pods on drones attached to arty units, will be used to pinpoint the location beyond LOS.

F22 one are different

 

[Kalkioftoday]

F22 one are different

Can you tell me more about it?

 

[arnabmit]

Both models are different

Then 1st one is probably a Long Rod Penetrator... APFSDS

 

[Lonewolf]

Can you tell me more about it?

Look closely

Type of radiating element is different , our is TSA shown in above post of karthi mentioned , the one used in f 22 offer bandwidth of 5 GHz bandwidth almost but bit different shape ,while vanila uttam mk1 barely reach 3 GHz .

Bor Conical Vivaldi offers a bandwidth fo nearly 10 GHz

When will conical vivaldi be ready

 

[Lonewolf]

When will conical vivaldi be ready

Already tested and fabricated , rest i don't know , maybe we see something soon

 

[Lonewolf]

One more thing I would add is that flexible electronics is another feild we have developed a lot , and credit goes to IITs (kanpur ,Bombay , Madras maybe ) , so next time some midget speaks that IIT are waste of money should look into that .

Flexibility electronic will help in conformal antenna development , and maybe conformal radar too , a radar element on the aircraft spine , interesting ?

Will help in achieving 360 active situational awareness .
