摘要
针对无人机上卫星数据链的实际应用情况,研究了卫星数据链的常用抗干扰措施,分析了各抗干扰措施的弱点及对抗策略,提出采用相关性干扰对抗卫星数据链,构建了基于时延的转发式干扰模型,对转发式干扰下的卫星数据链效能进行了分析和仿真。仿真结果显示,该方法能够有效对抗卫星数据链,具有一定的可行性。
According to the practical application of satellite data link on unmanned aerial vehi-cle, several common anti-jamming methods are researched. The weakness and combat strategy of anti-jamming method is analyzed. Correlation interference is proposed to interfere to satellite data link. The retransmitted jamming model based on delay is built. The efficiency of satellite data link in the presence of retransmitted jamming is analyzed and simulated. Finally, the simu-lation result shows the feasibility of this method for jamming satellite data link.
