摘　　要：针对现有的工业无人机导航接收机基本不具备抗干扰性能,无人机卫星导航信号易受干扰。研究在电磁干扰环境相对恶略情况下,依然能够捕获导航信号,能正常精确定位的抗干扰导航接收机,并可应用于无人设备,已经成为无人机卫星导航定位技术发展面临的重大课题。为此设计了一款小型化导航抗干扰接收机射频前端,最后对射频电路前端进行了测试,并给出测试结果,验证系统的可行性。The existing navigation receiver of industrial UAV has no anti-jamming performance,so the satellite navigation signal of UAV is easy to be interfered.The research of anti-jamming navigation receiver,which can capture navigation signal and locate accurately in relatively bad electromagnetic interference environment,and can be applied to unmanned equipment,has become a major issue in the development of UAV satellite navigation and positioning technology.For this reason,a miniature navigation anti-jamming receiver RF front-end is designed.Finally,the RF circuit front-end is tested,and the test results are given to verify the feasibility of the system.
