Fixed areas such as nuclear power plants, core combat zones, and sensitive infrastructure face per.sistent risks of illegal drone incursions. Once disrupted or attacked by drones, these areas may trig.ger severe consequences including nuclear safety accidents or military intelligence leaks . Suchzones often encounter coordinated swarms of drones, making traditional temporary countermea.sures inadequate for 24/7, all-directional, high-intensity defense needs . Consequently, establish-ing a long-term, multi-layered anti-drone defense system for fixed areas is essential.
