Abstract:

The rapid development of Unmanned Aerial Vehicle (UAV) technology has led to its continuous expansion in military and civilian fields, gradually becoming a powerful engine driving the development of low-altitude economy. Among the core components of UAVs, the satellite navigation system provides precise positioning and navigation information. However, due to the vulnerability of the satellite navigation system, satellite navigation often faces severe challenges brought by complex electromagnetic environments, causing UAVs to lose their positioning ability or deviate from the planned route, thereby seriously threatening flight safety and mission success rate. This paper systematically reviews the research status of anti-jamming technology for UAV satellite navigation systems. Firstly, starting from the main navigation interferences faced by UAVs, it analyzes the impact of oppressive interference and deception interference on UAV navigation systems. Secondly, it comprehensively summarizes the anti-jamming methods of UAV satellite navigation terminals. Regarding anti-oppressive interference, this paper focuses on discussing the technological progress at the receiving antenna end, radio frequency front end, and signal processing end. In terms of anti-deception interference, the methods of enhancing receiving processing capabilities and using advanced algorithms to detect and suppress deception interference are analyzed. In addition, the study studies the anti-jamming methods for UAV navigation in denied environments, including inertial navigation, visual navigation, celestial navigation, ultra-wideband, magnetic field navigation, radar navigation, and multi-information fusion navigation technologies. Moreover, for the formation navigation of multi-UAV clusters, the methods of inter-UAV cooperative and system improvement were explored to enhance the anti-interference capability of the entire UAV group. Finally, this paper identifies the current problems, outlines future research directions, and discusses potential technological advances. The research results of this paper not only provide a reference for the continuous progress of UAV navigation anti-jamming technology, but also offer theoretical and practical guidance for academic exploration and engineering application in related fields.
