| 摘 要： | 针对GNSS多天线转发式欺骗干扰在实际应用中，当干扰机与目标机距离大于一定范围时，将引起目标机钟差突跳，从而易被目标机检测和识别的缺陷，提出了基于干扰机阵列的转发式欺骗干扰新方法。干扰机阵列按照正六边形网型布设，可实现目标区域的无缝覆盖，并且灵活易拓展。不论目标机位于区域的任何位置，均有一个最优干扰机能够对其实施有效干扰。为了确定相邻干扰机的最优间距，本文在干扰机阵列不同间距下对具有钟差突跳自适应检测能力的目标机的干扰有效性进行了仿真研究。结论表明，综合考虑各种约束因素，相邻干扰机最优间距为17 km，满足该条件的干扰机阵列在实施欺骗干扰过程中，不会造成目标机钟差突跳，有效解决了该干扰方式易被目标机识别的问题。

| Abstract: | In order to solve the problem of clock jumping of the target receiver in the GNSS retransmission deception interference mode, which will result in the failure of jamming, a modified method based on jammer array is proposed in this paper. The jammer array could be set as regular hexagon, and the benefit is that wherever the target is, there will be one optimal jammer which can interfere with the target effectively. The simulation study is carried out to make sure the optimal space between neighbouring jammers. The conclusion shows that the optimal space mentioned above is 17 km. If the condition is fulfilled, the jamming from the jammer array will not lead to any clock jumping of the target receiver and the problem that the interference is easy to be identified is solved certainly. |
