Retrieval of Ocean Wind Speed Using Airborne Reflected GNSS Signals

Abstract: This paper develops the models that can be used in different flight scenarios to retrieve the wind speed using the width of the normalized delay waveform (NDW). First, the factors that influence the NDW width, including the wind speed, wind direction, flight height, and elevation angle, are analyzed. The contribution of each independent variable to the regression is explored. The results show that the wind speed, flight height, and elevation angle contribute more significantly than the wind direction so the wi… Show more

“…The concept of ocean altimetry using the GNSS-R was proposed by Martin-Neira in 1993 [2]. In recent years, GNSS-R technology has achieved rapid development, both in the measurement concepts, instruments, and applications, such as retrieving wind speed [3][4][5][6], measuring sea-surface level [7][8][9][10], estimating soil moisture and biomass [11][12][13][14][15][16], detecting oil spill [17], detecting sea ice [18], etc.…”
