A Distributed Interference Source Forwarding Deception Jamming Method Based on Spatial Domain

In recent years, due to the rapid development of UAV, numerous UA V black flying incidents have occurred, bringing many threats such as security and privacy infringement. Therefore, it is imperative to develop anti-UAV measures. This paper proposes a distributed interference source forwarding deception jamming method (DISJM) based on spatial domain to address the problems of strict limitations on the interference location of traditional single interference sources, easy detection by signal arrival angle detection modules, and poor interference concealment. This method eliminates strict limitations on the location of interference sources by placing them on concentric circles with inverted cones as the vertices in important places such as airports and large-scale events, and suspending them in the stratosphere, allowing for flexible station deployment. And by identifying and locating the target UAV, utilizing the location information of distributed interference sources, the airspace is divided to achieve the forwarding of complete constellation deception signals. The simulation results show that the distributed forwarding deception interference method based on spatial domain can accurately achieve delay control, achieve multi-domain fusion of forwarding deception signals in time-frequency domain, power domain, and spatial domain, successfully deceive the target UAV to the preset position, protect important areas, and effectively improve the concealment and interference success rate of deception interference signals.
