Jamming Technique to Link 11 Data Link

Starting with the mathematic-model of Link 11 data link,this paper analyzes its code error performance under the noise jamming,single-tone signal jamming and mufti-tone signal jamming.The simulation results shows that Link 11 system can be jammed by adopting the suitable mode:noise jamming or single-tone signal jamming multi-tone signal jamming if only the operating principle is held in the jamming technique to Link 11.From another point of view,by reason of the destructibility,many disadvantages of Link 11 system has already appeared,then a new system——link 22 system emerges,and its characteristics is simply analyzed.
