I. Military Domain: Revolutionary Breakthrough from Stealth Fighters to Battlefield Deception1. The "Smart Shield" of Stealth Fighters China's fifth-generation fighters, including the J-20 and J-35, are equipped with retractable Luneburg Lens systems, which dynamically adjust the Radar Cross Section (RCS) to achieve three tactical advantages: Training Mode: Retracting the lens hides the true stealth capabilities, preventing adversaries from deciphering critical parameters through radar monitoring.Transit Mode: Extending the lens amplifies the radar signal to civilian aircraft levels, ensuring air traffic control radars can track the fighters and avoid midair collisions.Tactical Deception: At the 2024 Zhuhai Airshow, the J-35A demonstrated its ability to simulate radar signatures of bombers, transport aircraft, and other targets—acting as a "Ra...

一、军事领域：从隐形战机到战场欺敌的革命性突破1. 隐身战机的“智能护盾” 中国歼-20、歼-35等第五代战机搭载的可伸缩龙勃透镜系统，通过动态调节雷达反射截面积（RCS），实现三大战术价值： 训练模式：收缩透镜隐藏真实隐身性能，避免核心参数被雷达监测系统破解。转场模式：展开透镜放大信号至民航客机级别，确保空管雷达有效追踪，避免空中碰撞风险。战术欺骗：2024年珠海航展展示的歼-35A，可通过调节透镜模拟轰炸机、运输机等不同目标特征，实现“雷达版孙悟空72变”。 2. 现代战场的“虚实博弈”俄乌战场实践：双方在无人机加装直径44cm的龙勃透镜，将小型无人机雷达反射面积放大至100㎡（相当于B-52轰炸机），通过制造大量虚假目标消耗敌方防空资源。靶机模拟：中国利用透镜反射器将低成本靶机RCS放大20倍，替代价值数亿元的大型靶机，单次训练成本降低80%。 二、民用通信：破解覆盖难题的中国方案1. 5G高铁覆盖里程碑牡佳高铁案例（中国首条全线路龙勃透镜5G覆盖高铁）： 覆盖性能：单基站覆盖半径从传统天线的600米...
