Experiments of sea surface altimetry using reflected GPS signals
In this letter, Global Positioning System (GPS) reflections for sea surface wind speed measurement are explored. The reflected signal correlation power is employed to retrieve the sea surface wind speed with a certain degree of accuracy. The GPS coarse-acquisition code autocorrelation sidelobe is studied and considered in the reflected signal model. This technique proves to be valid for the correlation power calculation. It is expected that this technique could further be studied for spaceborne applications with high dynamics.
