With the continuous improvement of Global Navigation Satellite System(GNSS)theory,the signal-to-noise ratio(SNR)of a GNSS reflectometry signal can be applied to detect snow depth.However,there are still some issues,such as insufficient observation data,low detection precision,etc.To solve the above problems,this paper uses the SNR reflectometry data of GLONASS L1 and L2 to detect snow depth in Yellowknife,Canada,from July 2015 to June 2016.
