Global Navigation Satellite System (GNSS) reflection signals could be used for sea-state sounding, for instance, the significant wave height. This paper introduced the observation equipment and the technical principle about the significant wave height sounding by GNSS reflected signals. By analyzing the data from Bohe experiment during 2009, we confirmed that the significant wave height was related to the significant coherence time of the interferometric complex field. An inversion formula was obtained by fitting the prophase data, and the results were compared with the data from Wave Monitoring System. The average deviation is 0.136 m with the relative standard deviations of 12.02%, and the root-mean-square error is 0.169 m.
