Research On RF-based Detection And Jamming For Unmanned Aerial Vehicles

In recent years,with the rapid development of the civilian UAV(Unmanned Aerial Vehicle)market,incidents of illegal flights by unmanned aerial vehicles have taken place.This poses a potential threat to both society and individuals as a result of major security risks and privacy violations.In response to these threats,this thesis explores how to detect and interfere with UAVs based on radio-frequence technology.Due to the wide variety of UAVs,a suitable UAV experimental research platform needs to be constructed or chosen.Firstly,this thesis investigates and analyzes several typical UAV platforms,finally builds a representative open source UAV platform and selects the mainstream commercial UAV platform as the experimental research object of this thesis.Based on these two types of UAV experimental platform,aiming at the problems of detecting and jamming UAV based on radio frequence,the contributions of this dissertation are as follows:1.This thesis realize the detection of APM(ArduPilotMega)open-source UAV by means of information interception.Firstly,the characteristics of this kind of UAV is analyzed in this thesis,and find out the loopholes of the communication for APM open-source UAV Then,this thesis designs and implements the detection platform and method for this kind of UAV based on the communication loopholes.Finally,the validity of the detection method is verified through experiments.2.This thesis designs and implements the interference hijacking method for APM open source UAV.Firstly,the interference method of hijacking attack and denial of service attack(DoS)is designed and implemented according to the concept of man-in-the-middle attack(MITM).Finally,the effectiveness of the interference hijacking method is verified through experiments.3.This thesis designs and implements the RF-based detection system and the corresponding detection method for commercial UAV platforms.Fistly,the RF-based detection system used to monitor the power of communication frequency band of commercial UAVs is designed and realized in this thesis.Then this thesis analyzes power variation features of the commercial UAV communication frequency band monitored by this system and designs the corresponding detection methods.Finally,the validity of this detection method is verified by experiments.
