摘要
针对无人机遥控遥测系统中的多径问题,本文分析了多径效应产生的原因并提出了解决方法。首先,从理论角度对无人机系统中多径效应进行阐述。然后根据理论依据提出减弱多径效应的方法。着重讨论其中的分集接收方法,从分集方式和合并方式两方面出发,分析比较各种方式的特点。最后,结合无人机遥控遥测的具体情况,讨论分集方式和合并方式的应用。
Aimed at the muhipath effects in unmanned aerial vehicle（UAV） remote control and telemetry, the reasons for muhipath effects are analyzed and the resolved methods are proposed. Firstly, the theory based on muhipath effects is introduced. Then, the diversity technology for reducing the effects is presented according to the theoretical bases. Among all the resolved methods, the diversity technology and the combination methods are analyzed. The features of the proposed methods are compared. Finally, the applications of all methods are discussed according to real project requirements.
