无人机测控与信息传输信道的建模与仿真设计

摘要

分析了无人机测控与信息传输系统中传输信道的特点,针对无人机飞行中不同的状态和环境条件,建立了不同的信道模型,并在此基础上,设计了一个可用于无人机测控与信息传输系统设计的信道仿真器,该仿真器通过设置不同的参数,可对无人机飞行中所处的不同通信信道进行仿真,以全面验证无人机测控与信息传输系统中所采用的传输技术性能及接收机性能.%In this paper, we analyze the channel characteristic of the telecontrol telemetry and information transmission system of UAV, and propose the different channel models by a series of flight status and environment. Based on the channel models, we design the relevant channel emluators that can emulate different communication channels by setting some parameters. The channel emluators can be used for the validation of the receiver performance of the telecontrol telemetry and information transmission system of UAV.
