摘要
文章将以分析欺骗干扰信号生成方式、干扰原理及其特点为出发点,提出用抛物线曲线拟合采样点的欺骗干扰信号检测算法,以实验所得结果研究该算法是否具有更高的拟合精度,可使干扰识别系统更容易发现欺骗信号,从而使后续对欺骗干扰的识别与排除工作更易进行,从而提升北斗导航系统抗欺骗干扰能力。
Based on the analysis of the generation methods,the principle and the characteristics of Spoofing signal, this paper proposes a kind of new spoofing detection algorithm which uses parabolic curves fitting sampling points, and show that whether the algorithm has higher fitting accuracy with experimental results. If so, the identification system would detect the spoofing signal more easily, and the anti-spoofing ability of the Bei Dou navigation system would be improved.
