研究了对塔康导航系统的干扰方法并对干扰效能进行了仿真评估.在分析塔康导航系统弱点的基础上,提出了对塔康信标台的饱和询问干扰样式和对塔康机载设备的基准脉冲欺骗干扰样式；建立了塔康信标台在压制干扰与饱和询问干扰条件下有效导航区域模型,基准脉冲欺骗干扰条件下无人机有效干扰区域的计算模型；设计了仿真方案并实施仿真实验,得出了不同干扰方式的干扰效能,通过对仿真结果的分析,得出了对信标台干扰时饱和询问干扰效果比噪声压制干扰效果好、对机载设备干扰时基准脉冲欺骗干扰为首选样式的结论.%Methods for jamming Tactical Air Navigation System ( TAC AN ) and the effectiveness of jamming were studied. The weakness of TACAN was analyzed, based on which a saturated asking method for jamming TACAN beacon and a reference pulse deceptive method for jamming TACAN equipment onboard aircraft were put forwarded. The effective navigation area model of TACAN beacon under the jamming was established, and the effective jammed area model of UAV was given too. Simulation experiments were carried out and the jamming effectiveness under different jamming modes was obtained. By analyzing the simulation result,the conclusions were obtained; 1) for TACAN beacon jamming,saturated asking method is superior to noise suppression in jamming effect; and 2) for equipment onboard aircraft jamming, reference pulse deceptive jamming method is the top choice.
