无人机通信链路欺骗技术

Unmanned aerial vehicle communication link deception technology

为了降低反制无人机时可能带来的附带损伤,提出一种通过合成假遥控信号欺骗无人机,夺取无人机控制权的技术。实验测量了两种无人机的遥控信号,对无人机遥控信号的调制方式进行分析,并总结归纳其特征,在此基础上提出对遥控信号特征参数的估计算法,对遥控信号进行解调,将解调数据与数据库中的通信协议进行比对,确定无人机的类型,合成相应的欺骗信号。按照制定好的欺骗策略夺取无人机的控制权。通过仿真和理论推导,证明了这种技术的可行性。

In order to reduce the collateral damage of anti UAV,propose a technology of deception UAV by synthesizing fake remote control signals.Measure two kinds of remote control signal of the UAV,analyze the UAV remote control signal modulation type,and summarized its characteristics,propose an algorithm for the estimation of the characteristic parameters of the remote control signals,demodulates the remote control signal,compare the data with the communication protocol in database,determine the type of UAV and synthesis fake signal to cheat UAV.The feasibility of this technology is proved by simulation and theoretical deduction.
