Study of a grid GNSS weak interference positioning method

  • 摘要: 介绍了网格化全球卫星导航系统(GNSS)弱干扰源定位的系统组成,针对该场景下现有方法对信噪比低的情况适应能力较差的问题,提出了一种基于信号噪声分离的差方均值函数拟合(MFDSS)的网格化GNSS弱干扰源定位方法,方法采用MFDSS方法实现时差估计,并利用Chan双曲线定位算法解算干扰源位置.文章对比仿真了该方法和常用网格化定位方法的定位效果,在对GNSS弱干扰源定位的场景下,该方法表现出优越性能.
    Abstract: This paper introduces the system composition of grid GNSS weak interference source location. Aiming at the problem that the existing methods have poor adaptability to low signal-to-noise ratio (SNR), this paper proposes a grid GNSS weak interference source localization method based on Mean Function of Difference Square based on Separation of signal and noise (MFDSS). The method uses MFDSS method to realize time difference estimation, and Chan hyperbolic positioning algorithm is used to calculate the location of interference source. This paper compares and simulates the positioning effect of this method and the commonly used grid positioning method. The results show that the method has superior performance in the GNSS weak interference source localization scene.
