小型无人机通信干扰器设计

A design of communication jamming device for small UAV

当今小型无人机存在监管难度大、安全系数低、缺乏规范等问题.为解决无人机监管困难、执法困难的问题,本文提出了基于无线通信干扰的无人机干扰方案.针对现有干扰方案手段单一,对各种型号无人机适用性差的问题,该方案首先使用压制式无线通信干扰方式干扰无人机控制信号,使无人机丧失通信能力;其次利用GPS转发欺骗信号对无人机定位进行干扰;最终无人机在多重错误控制信号的作用下迫降或坠毁.该方案的关键步骤是对无人机通信的干扰和伪GPS信号的生成,本文基于Simulink的实验仿真结果论证了该方案具有较高的可行性.

At present, the security problem of UAV is getting worse due to great difficulty in monitoring, low safety factor, lack of norms and other issues. In order to deal with the difficulty in monitoring, a small UAV interference program which based on the principle of wireless communication is proposed. The means of existing schemes are poor. To solve this prob- lem, firstly the program uses the barrage jamming method for radio communication to make the UAV lose the ability to communicate. Then use the GPS repeater deception signal to interfere the UAV positioning. Finally the UAV makes a forced landing or crashed in the role of multiple error control signals. The key step of the technique is to generate the inter- ference and pseudo GPS signal of the UAV communication. The experimental simulation results based on Simulink shows that the program is highly feasible.
