以全时段宽频压制式电磁干扰为主的无人机遥控链路对抗手段，对功率浪费较大且影响周围环境，采取跟踪式干扰并结合其干扰范围制定开机策略能够有效解决此问题。基于对无人机遥控数据链路实施跟踪式干扰的需求，从跟踪式干扰需满足的时域及功率条件出发，推导了跟踪干扰双曲面及有限功率干扰范围不等式，确定了不同参数条件下的有效干扰范围，从而提出了合理干扰开机策略。仿真实验结果表明，制定的开机策略与参数变化规律相符，对提高无人机电磁干扰效能具有指导意义。

As a main countermeasure mode for the UAV remote control link, the full time, broadband, suppressive electromagnetic jamming may waste jamming energy and have impact on the environment. Follower jamming and the turn-on strategy generated based on its jamming range can solve the problem effectively. In this paper, the follower jamming hyperbolic and the limited power jamming range inequation are conducted based on the time domain and power conditions of the follower jamming to the UAV remote control link. Accordingly, the effective jamming ranges under different parameters are confirmed and a reasonable jamming turn-on strategy is put forward. The simulation results show that the strategy can meet the changes of the parameters well, which is of great significance for improving the effectiveness of electromagnetic jamming.
