摘要
为使敌方侦察无人机抵近侦查时我方能快速反应,针对分布式欺骗干扰难以迅速部署并做出干扰的情况,研究了单站单通道下的全球定位系统(GPS)欺骗干扰.首先分析了该模式下欺骗位置与干扰机位置和欺骗信号延迟时间的关系;然后结合无人机导航系统及飞行控制原理,讨论了欺骗干扰对无人机导航系统的效果及定位被欺骗后的飞行情况,给出了单架干扰机利用单通道执行欺骗干扰的方法.仿真结果表明,该欺骗方法能够使无人机定位输出结果是干扰机的位置,并逐步诱骗敌方无人机至指定位置或区域内.
In order to make an immediate response when the enemy reconnaissance UAV approach and reconnoiter, and in view of the fact that distributed deception has difficulty in deploying rapidly and making timely jamming, this paper studies global positioning system (GPS) spoofing under single station and single channel. Firstly, the paper analyzes the relationship between spoofing position and jammer position and spoofing signal delay time in this mode. And then, combined with UAV navigation system and flight control principle, the paper discusses the effect of deception on UAV navigation system and flight situation after locating is deceived, and also presents a method of a single jammer using a single channel to execute spoofing. Simulation results show that the proposed spoofing method enables the UAV locating output to be the position of the jammer, and gradually lures the enemy UAV into the designated positions or area.
