| Abstract: | The ocean wind and wave sensing utilizing reflected signal from Global Navigation Satellite System (GNSS) provides a novel detection approach for marine meteorological observation, while the data analysis and validity verification are important to evaluate the performance of this technology.This paper introduces the sea wind detection mechanism using Beidou GEO satellites, and retrieves the sea wind based on the correlation time of the reflected signals of GEO satellite.The data collected by Beidou ocean remote sensing station of Shandong, which was set up for the demonstration of the Beidou application in oceanic, atmospheric and space monitoring and early warning program, are analyzed and compared with standard data, and the results prove the validity of the proposed method and the system. |
