We've learnt from the masters(Russians/Israelis/French) and refined their systems/techniques with our own. Even our EW pods for MKI and Tejas are inspired by both the Israeli ELTA-8222 and SPA-518. But the end result is much kickass and better than both.That previous webinar , Prof Debi Prasad Mishra mentioned that in a lot of fields we are followers, not leaders. But in fields like hypersonics & radio comm we might become the leader. I guess the same goes for EW systems.
