摘要
随着科技发展,无人机开始越来越多地出现在现代战场中,能够在通信链路中继、高空侦察等方面发挥重要作用,但对无人机的指挥控制极度依赖通信链路,因此提高无人机数据链的抗干扰能力成为关键,通过分析战场电磁环境和现有的抗干扰技术,提出了一种基于无人机的自适应跳频抗干扰技术,经过理论计算和实验室仿真分析,该技术能提高无人机通信链路的抗干扰能力。
With the development of science and technology,unmanned air vehicles(UAVs)have been applied to modern battlefield in increasing numbers.They can play an important role in communication link relay and high-altitude reconnaissance,but the command and control is extremely dependent on the communication link.Therefore,improving the anti-jamming capability of UAV data link becomes the key.This article proposes an adaptive frequency hopping anti-jamming technology based on UAVs through analyzing the electromagnetic environment of battlefield and existing anti-jamming technology.The anti-jamming ability of the UAV communication link can be improved by the technology through theory calculation and laboratory simulation analysis.
