Aimed at multiple events of spoofing and trapping of unmanned aerial vehicles (UAVs)in battlefields of Syria and Iran, this paper illustrates the method，mechanism and effectiveness of GNSS generated spoofing jamming and repeater spoofing jamming, and proposes the method of intelligent coherent tracking spoofing. Through the analysis of the mechanism of the intelligent coherent tracking spoofing jamming and the influence of the satellite navigation user receiver, the intelligent tracking and traction effect of the spoofing jamming on the user receiver are studied in the paper. Finally, the simulation tests are completed to verify the spoofing ability, destructiveness and concealment of the spoofing jamming.
