Oh I see.And don't feel sorry brother.I say you sorry if I offended you,it was not my intention.
Okay,take a look at their A 50 AWACS - it's primary sensor is a mechanically steered antenna housed inside a rotodome.
On the other hand,DRDO has already developed the S band radar for the Emb 145 AEW&CS.
Besides,most of the Russian ground radars, although quite high powered are still based on PESA technology.
On the other hand,we are moving ahead with AESA radars both domestic (look at the Defexpo 2014 LRDE posters) and Israeli ones.Now I'm not implying that an AESA is better than PESA but still you can not deny the fact that an AESA radar will always have better growth potentials compared to mechanical or passive electronic radars.
And we no longer are using the original Green Pine which by now has become a dated design.The sensor network for exoatmospheric interception leg of our BMD system is based around the Sword Fish LRTR which is far more bigger and has greater power output.It's TRMMs has been totally indigenised by LRDE.Infact LRDE had patented its first working solid state GaAs TRMMs,both S band and L band way back in early 90s.
And coming to canisterisation,it's not that big a problem since L&T already produces a variety of canisters for different missiles like Brahmos,Nirbhay,Prahaar and K 15 Shaurya to name a few.
