Warning light indicating danger of laser exposure. Warning system is any system of biological or technical nature deployed by an individual or group to inform of a future danger.
PAVE PAWS (PAVE Phased Array Warning System) is a complex Cold War early warning radar and computer system developed in 1980 to "detect and characterize a sea-launched ballistic missile attack against the United States". [1] The first solid-state phased array deployed [2] used a pair of Raytheon AN/FPS-115 phased array radar sets at each site ...
VHF (-M/-VP) radar. UHF (-DM) radar. Voronezh radars (Russian: РЛС Воронеж) are the current generation of Russian early-warning radar, providing long distance monitoring of airspace against ballistic missile attack and aircraft monitoring. The first radar, in Lekhtusi near St Petersburg, became operational in 2009.
