Research on Narrowband Interference Suppression Technology of UAV Network Based on Spread Spectrum Communication

With the rapid development of information technology and the increasing application of unmanned aerial vehicle (UAV) in various fields, UAV network is facing many challenges, such as complex electromagnetic environment, serious environmental interference and human interference. Therefore, higher requirements are put forward for its safety, reliability and adaptability in complex environment. In order to improve the anti-narrowband interference capability of UAV network, this paper proposes a narrowband interference suppression technology based on spread spectrum communication. The simulation results show that the method has a good effect on narrowband interference suppression, and provides an effective solution to the problem of narrowband interference suppression in UAV network.

I. Introduction

In recent years, the application of UAV is developing rapidly, which has great potential in military and civil fields. As the volume of UAV becomes smaller, the perception ability becomes stronger, and the autonomy becomes higher, the UAV network composed of multiple UAVs is becoming a research hotspot in the field of UAV. The multi UAV cooperative self-organizing network can accomplish tasks more reliably, efficiently and economically than the single large UAV. At present, the mode of multi UAV cooperation has been widely used in the film and television shooting, agricultural monitoring, meteorological monitoring, forest fire detection and emergency rescue and other fields [1], [2].
