[1]提出了一种滤除全球导航卫星系统(GNSS)信噪比(SNR)数据中多径效应的方法。该滤波器干净地去除了多路径，既不影响缓慢变化的趋势(如对流层吸收或卫星范围的变化)，也不影响高频分量(如电离层闪烁)，因此在空间气象研究中可能有用。类似地，从输入数据移除的多路径数据失真最小，并且包含关于多路径几何的有用信息。描述了一种使用频谱分析的形式来定位反射对象的方法。
[1] A filter to separate the effect of multipath in Global Navigation Satellite System (GNSS) signal-to-noise ratio (SNR) data is presented. The filter removes multipath cleanly, and affects neither slowly varying trends (such as tropospheric absorption or variation in satellite range) nor high frequency components (such as ionospheric scintillation), and so is potentially useful in space-weather research. Similarly, the multipath data removed from the input data is minimally distorted, and contains useful information as to the multipath geometry. A method to locate reflecting objects using a form of spectral analysis is described.
