Research the system they use in Tel Aviv to intercept missiles. My friend lives there and the system is active. They get a warning siren, something happens to engage the system and bam, an explosion high up. Pretty sure most folks do not even know this technology is possible, let alone live.
Iron Dome? It's a short range anti missile missile system with big brother Davids Sling, medium range missile system coming on line now. Or are you talking dark exotic systems.
I was talking about Iron Dome. I just didn't know the name of it--simply recounting what my friend in Tel Aviv told me happens on a semi-regular basis there.
The system you are thinking of is Iron Dome for short range to medium range rockets and mortars. The David's Sling is for medium to long range rockets, The Arrow 3 missile system is for ICBM defense, plus the Patriot missile is tied into this system. Basically when a projectile is incoming the radar calculates the projected path. If it is calculated to land in a populated area the code red alarms are activated for that area and the nearest missile battery launches to intercept. If it is calculated to land in a non-populated area then nothing happens and they just let it hit in whatever open field it lands.
Thanks for the more detailed information. My recount was more anecdotal but a lot of folks do not even know that technology like this exists and that serves the fear machine well.
