摘　　要：Link16数据链采用扩跳结合的体制,普通的手段难以有效地对Link16数据链信号进行侦收截获,针对此问题提出一种基于信道化滤波的方法,实现Link16数据链信号的全频点全概率实时接收。在此基础上,分析针对扩跳体制信号的干扰方法,针对Link16信号数据帧中采用8个频点进行数据同步的特点,提出采用同步信道的Link16信号干扰方法。通过仿真证明了该方法的有效性和可实现性,为Link16数据链电子对抗提供新的手段。Link16 data link adopts DS and FH system,and it is difficult to effectively detect and intercept Link16 signal by traditional means.Aiming at this problem,a new method based on channelization filter is pro⁃posed,which can realize the full-frequency full-probability real-time reception of Link16 signal.On this basis,the jamming method for signal of DS and FH system is analyzed.Aiming the characteristic of Link16 using 8 synchro⁃nous channels,a synchronous channel jamming method is proposed.The effectiveness and reliability of this meth⁃od are proved by simulation,which provides a new mean for electronic countermeasure of Link16.
