You are only quoting to make fun you did not understand my post.
if you have something to discuss then quote me
DRDO will be challenged by Military to prove it's worth.
And yes there is no problem to build an array of such radars across border
1. I did understand your post. You didn't get what I was saying.
2. DRDO will be challenged and so will be any other vendor.
3. Keeping such radars operational all the time has running cost implications, setting them up is not a big issue.
