that is old news dude. the russians created a kind of system like that in the mid 80s. is was called "Drozd" (thrush). then, in the 90s they creaded a new one, called "Shtora" (curtain)
the method is easy. when an RPG or a missile is flying at it, it's radar spots the missile (target) (it detects the speed - all objects like birds are not understood as targets, becawse they do not fit in the speed limit). then it automatically (cuz human reaction is too slow) turns the tank turret to the side from where the missile is flying. then, a special projectile is shot in that direction (it doesen't 100% calculate the position of the missile, it just says approximetly +/- 1 meter). this projectile flys a bit & explodes in some distance from the tank. this projectile is made so when it explodes it fires like a shotgun in the direction at wich it's flying- a lot of small fast shards hit the rocket, making it explode not in the correct range. (if you didn't know, to penetrate the armour, the rocket must explode in about 30 cm from the target. this is needed to maximally form the penetrating jet, but that's a different story)
btw, if you stand near the tank you can get kileld by this system.
i can tell a lot about Chineese system of protecting a tank from missiles, but i won't make a topic for that
this is just REALLY OLD news. the Chineese made a fundamental breakthrough, i think.
