Aiming at studying the jamming methods of Link16 system, the anti-jamming techniques adopted by Link16 are studied and a simulation model is established in the paper. Based on the conventional static multi-tone interference which is used frequently at present, a new dynamic jamming method named Frequency Hopping Collision (FHC) interference is put forward. The features and jamming performance of FHC interference in the condition of different frequency hopping rate are analyzed and simulated. According to the analysis and simulation results, the jamming performance, advantages and disadvantages of the two jamming methods are compared in the same conditions. It is concluded that the new FHC interference has advantages over multi-tone interference from the aspects of utilization rate of jamming power and complexity of realization in jammer and also provides a new way for the jamming of Link16 system.
