Abstract: The article introduces the basic principle of the significant wave height measurement using GNSS-R signals based on the autocorrelation time method of the Interferometric Complex Field(ICF). Making use of Oceanpal GNSS-R receiver on teaching-training vessel of Dalian Maritime University, the first ship-borne measurement experiment of china has been done. By analyzing the datas collected from Oceanpal receiver and Miros wave extractor installed on the ship, consistency between the two datas proves the feasibility of ship-borne measuring platform and provides basis for the further study on ocean dynamical environment observing using GNSS-R signals.
