摘　　要：提高无人机系统抗电磁干扰能力,是适应信息化战争复杂战场电磁环境的必然要求。分析了传统无人机接收前端的不足,在此基础上,介绍了一种YIG调谐的、能够有效抑制干扰的高频接收前端的实现方法,并给出了设计方案及关键技术。该射频前端特有的超宽带,不仅包括了多个型号现役无人机的工作频带,而且其多通路窄带控制模式,以及其适应恶劣环境温度的特性,都极大地提高了无人机的多系统兼容能力。It is necessary to improve the anti-electromagnetic interference ability of unmanned aerial vehicle（UAV） system to meet the requirement of complex battle field electromagnetic environment.Based on the analysis of deficiency of traditional UAV＇s RF front end,this paper introduces an improved solution with tuning by YIF,which can suppress interference effectively.The solution is described in terms of the key techniques and designed solutions.This RF front-end has a ultra wide operating band that covers operating frequency ranges of several types of UAV.The RF Front end improves electromagnetic compatibility through multi-way distributive narrowband channels and capability which makes the system be able to adapt to bad environment temperature.
