Dodging an incoming RPG is a pretty tall task for anyone, unless you're a ninja on meth. For the rest of us, it'd be easier to just blow up the damm thing before it hits, right?That's the Iron Curtain system in a nutshell: It uses "active protection" technology to blow RPGs and anti-tank missiles out of the air, like if you were to punch somebody's fist that was about to punch you. What's surprising is that the chief bottleneck for this kind of tech isn't lightning reflexes or propulsion or clairvoyance or some other engineering obstacle: It's pure processing power.
The computer has to register the target, calculate its airspeed and trajectory, and then decide where to shoot back. The Iron Curtain is mounted on the top of armored vehicles, and it fires straight down. The close proximity to the vehicle drastically reduces the complexity of the physics involved, though it also puts more em
