面向领导跟随无人机蜂群的定向驱离攻击方法

Directional expelling attack on unmanned aerial vehicle swarm with leader-follower structure

针对领导跟随结构的无人机(UAN)蜂群,提出了一种基于欺骗信号的定向驱离攻击方法。首先,构建了虚假偏差信号和给定状态信号这2种欺骗信号模型;其次,给出了2种欺骗信号攻击下实现无人机蜂群定向驱离的充分条件;最后,确定了无人机蜂群定向驱离后运动轨迹中心函数的显式表达式,分析了2种欺骗信号对定向驱离后无人机蜂群运动轨迹的影响,其中,虚假偏差信号攻击后无人机蜂群的运动轨迹受到所有虚假偏差信号平均值的影响,给定状态信号攻击后无人机蜂群的运动轨迹由攻击者预设的参考轨迹决定。仿真实验验证了所提出的理论成果的正确性。

A directional expelling attack method for Unmanned Aerial Vehicle(UAV)swarm with leader-follower structure based on the deceptive signal is proposed.Firstly,two types of deceptive signal models,namely false deviation signal and given state signal,are constructed.Secondly,sufficient conditions for achieving UAV swarm directional expelling under two types of deceptive signal attacks are provided.Finally,the explicit expressions for the center function which determines the motion trajectory of the UAV swarm after directional expelling are determined,and the effects of two types of deceptive signals on the motion trajectory of UAV swarm after directional expelling are analyzed.It is found that the motion trajectory of the UAV swarm after being attacked by the false deviation signal is affected by the average value of all false deviation signals,however,the motion trajectory of the UAV swarm after being attacked by the given state signal is determined by the reference trajectory preset by the attacker.Numerical simulation is conducted to verify the effectiveness of the theoretical results.
