somebozo and gurudutt, read post # 66. Guru it is not easy, its is not sci-fi movie. United States has a complete Project for Cruise Missiles Defenses alone dedicated to detect, trace, track and intercept destroy. According to US it is a daunting difficult task which requires dedicated teams money and time and ofcouse technology. I am giving you example of US because their research institutes are taking CMs potentially dangerous element in attacking and destroying home land. There have been numerous research papers published. india and Pakistan currently lacks the advanced systems state of the art Real-Time Integrated Battle Management Systems in-time both countries will have them covering larger areas connected but it is too early both are in progress working on it. Shourya will be same as Babur and Tomahawk. Yes 100 Babur can cause havoc phalcons can only do so much if you read my post #66 you will understand how things work.
It would be unsually foolish of Pakistan to develop BMs and CMs and neglect SAMs don't you think a country that is investing in BMs and CMs also might have invested in SAM Systems of High and Low altitudes, lets look it this way its a network of web spread across Areas a surprise.
SPADA 2000 and HQ-18 two potential SAM Systems with SPADA 2000 being medium range interceptor where as HQ-18 you can research but its potentially on the table.
In sum, the cruise missile surveillance mission is best accomplished with look-down, ground-clutter-filtering radar augmented by imaging infra-red sensors, mounted on an aerial platform that is as persistent as possible, with the lowest possible operating costs.
Next comes Interceptors to shoot down Cruise Missiles, once cruise missiles are traced, detected and tracked.
