摘　　要：介绍Link11数据链的组成和Link11数据链工作方式、消息格式、副载波、同步方式、纠错能力等特点。从误帧率的角度分析了对Link11数据链的同步音干扰、数据音单音干扰和数据音多音干扰的干扰效果,并对比了噪声干扰和伪码干扰的误帧率性能。分析表明,干信比较大时,多音干扰效果优于同步音干扰和单音干扰,伪码干扰效果优于噪声干扰。The composition and characteristics, such as operating methods, message format, sub -carrier modulation, synchronizing mode and error correction of Link 11 data link are de- scribed. Meanwhile, the jamming effect against synchronizing tone, data single-tone and data multi-tone of Linkl 1 is analyzed in the term of frame error rate, it shows that the multi-tone jamming effect is better than synchronizing tone jamming effect, and pseudo code jamming effect is better than noise jamming effect when the jamming-signal ratio is relative large.
