It's Dipole antenna which are limited by their bandwidth compared to other like slot, Vivaldi.

Is the LLLWR an indigenous replacement for the BEL/Leonardo DRS NMHR?

Also Talon was supposed to be for Su30MKI--they appear to now have dropped that from the marketing. Is anyone in the know what else they're pursuing?

So Virupaksha is not based on the latest architecture?

The uttam tender was the older tender. Since then uttam mk1a and uttam mk2 have both come out using the new improved architecture. Im Not usre if uttam mk1a was planned for GaN because the mk1 was only GaAs but the mk2 100% is.

The virupaksha is just a drastically upgraded version of the mk2 using the superior hardware base of the su30mki that has a lot of space and power.
The new DRDO photonic radar is also at like TRL 7 right now and thye plan to make that airborne as well. Dont know the exact timelines though and honestly for frontier tech like this I don't think they know either.

So Virupaksha is not based on the latest architecture?

Would be amazing if this LLLWR can be transported via drone to the forward areas along with the DG set.

Data Patterns Q1 Concall

Hawk radar

Sure. We’ve done the hardware for both the MiG as well as Su-30, but we need the software for them. Original concept was we get the software from somebody. It didn’t work out, the hardware we contain and develop is world-class. We are in discussion with DRDO to see whether we can collaborate with them for putting this together. We are also in discussion with the Russian counterparts on the OEMs to see whether both are going ahead. I can’t very clearly say which will happen when faster. We expect the next two to three months time should get some breakthrough in this. The software can be ported, and we go to flight trials after that. We’re also investing in next generation, the HAWK program, next generation radars, which will be what is production-oriented line.​
