Quantum Communication Empowered Radar Omni-Directional Detection and Directed Energy Defense System
I. Technical Integration Principles
1. Quantum Communication Enhanced Radar Network
Quantum Key Distribution (QKD) establishes anti-jamming communication links, enabling "one-time pad" encrypted radar data transmission within a 1,200 km range, maintaining stability even under intense electromagnetic interference.
Quantum Teleportation breaks traditional optical fiber limitations, achieving instantaneous quantum state synchronization across radar nodes to build a distributed network with 360° full-domain coverage.
2. Omni-Directional Quantum Radar Detection
Quantum Entangled Photon Pairs detect stealth targets by capturing perturbations to quantum-state photons, neutralizing F-35-class stealth coatings with 1,000× higher sensitivity than conventional radar.
Quantum Superconducting Detectors enable real-time tracking of stealth fighters at 800 km range (validated in Northwestern test sites) with centimeter-level resolution, providing sub-second target locking for directed energy strikes.
3. High-Energy Directed Defense
High-Power Microwave Weapons focus energy into a 0.1° beam angle with gigawatt (GW)-level instantaneous output, intercepting hypersonic missiles effectively.
Laser Defense Systems coordinate multi-node energy superposition via quantum communication networks, forming a 10 kJ/cm² energy barrier over 100 km for 30 seconds to neutralize drone swarms.
