btw,did you happen to go through two of the latest radar systems revealed by LRDE in def expo 2014?namely arudhra and ashwin?both of them feature DBF(digital beam forming)- something unprecedented in any indian designed AESA/PESA so far.This allows impressive control of beams emanating from every single element as you now have got A/D converter attached to every radiating element!
arudra has an instrumented range of 400kms and can track more than 200 targets at any given time whereas ashwin is a light weight AESA than has a range of 200kms and can track >200 targets at any given time.
This is the first time when LRDE has designed a truly "multi-functional" AESA capable of performing a variety of tasks simultaneously
Since someone just above mentioned the need for pakistan to have a SAM system,i would like to add that SAM can not be designed without designing an effective radar system
