摘要:
欺骗式干扰通过发射与真实卫星信号相似的信号误导接收机产生错误的定位结果，具有极大的危害。该文针对转发式欺骗干扰，提出一种基于信号重构的单天线欺骗干扰抑制方法。该方法首先通过参数估计方法估计出欺骗信号载波频率和码相位，然后构建欺骗信号子空间正交投影矩阵以抑制干扰。仿真实验结果表明该方法对欺骗干扰具有良好的抑制效果，能够保障接收机在干扰环境中实现有效定位，并具有较低的运算复杂度。
Abstract:Spoofing misleads the receiver to generate the wrong position information by trans-mitting signals similar to authentic satellite signals, which has great harm. In this paper, a single-antenna spoofing mitigation algorithm based on signal reconstruction is proposed for meaconing. Firstly, the carrier frequency and code phase of spoofing signal are obtained by parameter estimation method, and then the orthogonal projection matrix of spoofing signal subspace is constructed to suppress spoofing. The simulation results show that the algorithm has a good suppression effect on spoofing and ensure the receiver can locate effectively in the interference environment, and the algorithm also has lower computational complexity.
