| 摘要: |
| 无人机(Unmanned Aerial Vehicle，UAV) 凭借其卓越的机动性能、快速部署特性以及经济高效的优势，已在军事侦察、灾害救援、农业植保、物流运输及影视航拍等多个领域实现规模化应用，成为现代智能装备体系中的重要组成部分。但在复杂的现实环境中，UAV的视距通信链路易被障碍物阻挡，造成通信阻塞，服务质量下降。针对这一问题，学者们提出了智能反射表面(Reconfigurable Intelligent Surface，RIS) 辅助的UAV数据传输与计算系统，不仅解决了UAV视距局限的问题，还为优化UAV能耗、提高计算能力和通信安全性提供了一系列创新解决方案。首先，调研了近年来该领域的研究现状，介绍了当前RIS辅助的UAV系统研究成果与进展，探讨了单/多RIS辅助的单/多UAV系统的各自优缺点。其次，分析了不同系统在优化目标、优化变量、RIS位置、地面收发点状态以及UAV飞行状态等方面的差异性与单一研究片面性，概括了各类系统研究现状与不足。最后，提出了该领域目前的研究难点和挑战，并进一步讨论了未来潜在的研究方向。 |

| Abstract: |
| Unmanned aerial vehicle(UAV) has achieved large-scale application in many fields such as military reconnaissance，disaster rescue，agricultural plant protection，logistics and transportation，film and television aerial photography，and has become an important part of modern intelligent equipment system by virtue of its excellent mobility performance，rapid deployment characteristics and economic and efficient advantages.However，in the complex real environment，the UAV’s line-of-sight(LOS) communication chain is blocked by obstacles，resulting in communication congestion and communication quality degradation.To solve this problem，scholars have proposed a UAV data transmission and computing system assisted by reconfigurable intelligent surface(RIS)，which not only solves the problem of the limited LOS of UAV，but also provides a series of innovative solutions for optimizing UAV energy consumption，improving computing power and communication security.Firstly，the current research status in this field in recent years is investigated，the current research achievements and progress of RIS-assisted UAV systems are introduced，and the advantages and disadvantages of single/multi-RIS assisted single/multi-UAV systems are discussed.Secondly，the differences of different systems and the one-sidedness of a single study are analyzed in terms of optimization objectives，optimization variables，RIS position，ground transceiver point status and UAV flight status，etc.，so as to summarize the research status and shortcomings of various systems.Finally，the current research difficulties and challenges in this field are put forward，and the potential research directions in the future are further discussed. |
