基于时延控制的GPS转发欺骗干扰技术

针对采用GPS转发欺骗干扰技术对GPS用户进行干扰时存在定位跳变的问题,提出一种基于时延控制的GPS转发欺骗干扰技术。针对定位和转发欺骗存在的不足,采用迭代算法并引入偏移率参数对GPS信号附加时延进行处理,优化了GPS转发欺骗干扰技术。结果表明:采用逐点变化时延算法的干扰机对长距离飞行用户进行欺骗干扰时,用户没有出现定位跳变,目标位置与用户真实位置存在较大的偏移距离,干扰效果明显,增强了转发欺骗干扰技术的隐蔽性。

GPS Repeater Deception Jamming Technology Based on Delay Control

When using Global Positioning System (GPS) repeater deception jamming technology to GPS user's interference, there is a problem of positioning jump, this paper proposes a GPS repeater deception jamming technology based on delay control. Considering the deficiency of location, iterative algorithm and deviation parameters are used to handle the additional GPS signal delay, this algorithm optimizes GPS repeater deception jamming technology. Theoretical study and simulation results show that: When deception jamming using point change time delay algorithm,the user did not appear positioning jump, target position have a larger offset distance and interference effect is obvious, this technology enhances the concealment of repeater deception jamming technology. The GPS repeater deception jamming technology based on delay control has better feasibility and application value for users who have longer flight time.
