摘要
针对现存的智能抗干扰方法难以对抗高速跟踪干扰的问题,提出了一种主动的基于干扰利用的抗干扰方法。为了实现该方法,提出了一种增强型差分跳频(EDFH)框架,该框架在传统的通信信号传输的基础上增加了训练信号的发送和处理过程,并在接收端设计了针对用户信号与干扰信号的混合信号匹配滤波器(CMF)。仿真结果表明,该方法在对抗高速的跟踪干扰时表现出良好的性能,并且随着干扰信号速度和功率的增加,其通信性能也显著提升。
In order to solve the problem of the existing anti-jamming methods have difficulty against high-speed reactive jamming,this paper proposed a new method to leveraging jamming instead of avoiding jamming.To achieve this goal,it proposed an enhanced differential frequency hopping,which added the process of sending and processing training signals.In EDFH,it designed the frequency detection at receiving end to detect the combined signal(user signal plus jamming signal).It also designed a combined-signal matching filter at the receiver to improve the detection performance of the combined signal.Simulation results show that the proposed method performs well in combating high-speed reactive jamming,and the leveraging effect is also apparent as the communication performance increases as the speed and power of the jamming signal increase.
