低空无人机反制关键技术发展研究OA

With the rapid development of the low-altitude economy and the increasing proliferation of unmanned aircraft system(UAS)technologies,low-altitude security issues have become increasingly prominent.UAS possessing low,slow,and small characteristics,if used illegally in sensitive areas,will pose a severe threat to public safety,aviation order,and even national security.Therefore,developing efficient and reliable low-altitude counter-UAS technologies has become a critical support for ensuring the healthy development of the low-altitude economy.This study reviews the development status of counter-UAS technologies.It first sorts out non-cooperative airspace surveillance technologies,including radar,radio frequency signal monitoring,optic identification,and acoustic detection,summarizing the principles,advantages,and limitations of various sensing methods.Moreover,it explores the current research status of enhancing sensing capabilities through multi-sensor information fusion.Subsequently,from the perspective of cyber-physical systems,the study evaluates the technical characteristics and application challenges of counter-UAS measures at both a physical layer(e.g.,lasers,microwaves,net capture,drone collision)and a cyber layer(e.g.,communication jamming,GNSS spoofing,acoustic interference).The study indicates that current low-altitude counter-UAS technologies still face challenges in terms of detection and response.To address these challenges,this study proposes recommendations from a technological development perspective,including the adaption of sensing technologies to specific scenarios,pilot deployment of networked low-altitude surveillance equipment,optimization of counter-UAS measure combinations,in-depth research on counter-UAS mechanisms,risk management during counter-UAS operations,and multi-platform collaboration.This study aims to provide a reference for the development of low-altitude counter-UAS technologies through a systematic review,thereby contributing to the establishment of a safe,reliable,and efficient low-altitude security system and ensuring the sustained development of the low-altitude economy.
