China develops UAV defenses from spoofing detection to covert links and shipboard landing

Simulation tests on 30,000 flight segments achieved trajectory prediction accuracy above R = 0.99 and spoofing detection with 98.4 percent accuracy, while reducing off-course distance by 26 percent compared with baseline methods. Meanwhile, Dr. Fangtao Yang and colleagues surveyed the fast-growing field of covert UAV communications. Because line-of-sight wireless links are highly exposed, covert approaches aim to conceal transmissions entirely, preventing interception attempts. Together these advances outline a multi-pronged strategy for UAV resilience: anomaly detection to expose spoofing, covert communications to shield wireless links, and predictive control to enable safe landings in dynamic maritime environments.
