For cruise missile defence the tracking it is the most crucial aspect which can be acheived by large number of land based radars,aerostats,awacs and male drones.Once tarcked it can be easily shot down(because of it's slow speed) with land based interceptors or even air to air missiles from a fighter plane.But for ballistic missiles tacking the taget is only the first part because intercepting those high speed warheads hurtling down with a speed of mach20+ requires first grade interceptors which is like hitting a bullet with another bullet.Now drdo has shown us the capability of shooting down ballistic missiles and surely it can deliver on the cruise missile front provided india has sufficient surveillance platform to tack a cruise missile.
