卫星导航系统抗干扰问题研究

摘要

Aiming to deal with the vulnerability of the satellite navigation system, this article made a comprehensive study about its anti-jamming technology, which focusing on in-troducing and analyzing the anti-jamming technology of receiver antenna, radio frequency (RF) front-end, baseband processing unit and the adaptive filter technology .The types of repressible jamming signals, anti-interference principles, and development status of current anti-jamming techniques were also reviewed .Research hotspots and problems of anti-jam-ming techniques for narrow band interference, broadband interference, and multipath inter-ference were summarized and the development tends of anti-jamming technology were dis-cussed.%针对卫星导航系统的脆弱性和干扰来源，对卫星导航系统的抗干扰技术进行了研究，重点对接收机天线、射频前端、基带处理三大模块的抗干扰技术以及自适应滤波技术进行介绍和分析，对各类抗干扰技术所能抑制的干扰类型、抗干扰原理、发展状况进行阐述。分别总结了窄带干扰、宽带干扰、多径干扰适用的抗干扰技术、研究热点及存在的问题，提出了卫星导航系统抗干扰技术的发展趋势。
