According to the multi-target unmanned aerial vehicle uplink tracking interference method based on the frequency hopping pattern provided by the invention, a frequency hopping signal presents a periodic occurrence rule in each sub-channel, and the periods are all frequency hopping sequence periods, so that tracking interference on the whole single unmanned aerial vehicle frequency hopping link is realized by completing tracking interference on each sub-channel periodic signal. Based on the characteristics, the problem of tracking interference on multiple unmanned aerial vehicles is converted into the problem of tracking interference on various periodic signals under different sub-channels by dividing different sub-channels and dividing different tracking and interference threads under the same channel, and the tracking interference on the multiple unmanned aerial vehicles can be realized under the condition that the time-frequency domain distribution of frequency hopping signals is complicated. Under the condition that the accurate hopping period parameter is unknown, the hopping time of the frequency hopping signal is tracked, the communication link of the multiple unmanned aerial vehicles is accurately interfered, the interference response time is short, the interference efficiency is high, and therefore the multi-unmanned aerial vehicle countering task is better completed.

    本发明提供一种基于跳频图案的多目标无人机上行链路跟踪干扰方法,跳频信号在各子频道呈现周期出现规律,且周期均为跳频序列周期,故对各子频道周期信号完成跟踪干扰即实现对单无人机跳频链路整体的跟踪干扰。基于此特点,本发明通过划分不同子频道以及在同频道下划分的不同的跟踪及干扰线程,将对多无人机分别进行跟踪干扰的问题转化为在不同子频道下对各类周期信号进行跟踪干扰问题,可在跳频信号时频域分布复杂的情况下,在未知准确的跳周期参数情况下,对跳频信号的跳时刻进行跟踪,对多无人机的通信链路进行精确干扰,干扰响应时间短,干扰效率高,从而更好完成多无人机反制任务。
