A Review of Research Progress on UAV Free-Space Optical Communication Systems
摘要
Abstract
Unmanned Aerial Vehicle(UAV)-enabled Free-Space Optical(FSO)communication,owing to its high bandwidth and strong security,has emerged as an important research direction in integrated space-air-ground-sea communication networks.However,although UAV platforms offer high mobility,their limited stability causes optical links to exhibit pronounced time-vary-ing and non-stationary characteristics under atmospheric turbulence and pointing errors,thereby severely constraining the system reliability.This paper reviews the research progress in UAV-FSO communication systems from the aspects of system architec-tures,channel characteristics and fading modeling,Pointing,Acquisition and Tracking(PAT)technologies,and typical applica-tion scenarios.It focuses on the modeling of atmospheric turbulence,platform jitter,and angle-of-arrival fluctuations,as well as their effects on link performance.It also summarizes recent advances in PAT techniques,including predictive control,opto-me-chanical cooperative compensation,and intelligent tracking.In addition,the characteristics of UAV-FSO applications in emer-gency communications,aerial collaboration,long-distance backhaul,and high-reliability communication support are discussed.Finally,the major challenges in system-level collaborative optimization,physical validation in complex environments,and engi-neering implementation are identified,and future research trends are outlined.关键词
