Sea wave height retrieving system based on GNSS-R carrier phase

The wave observing instruments invented by our team were firstly used in the Global Navigation Sateuite System-reflection(GNSS-R)remote sensing system located at Shanghai East Ocean Bridge.Firstly,a new sea surface reflected model for GPS signal,as well as sea surface height(SSH)retrieving method based on dealing with the difference between the Global positioning System(GPS)carrier phase differences was given.GPS direct and reflect signals received by right hand circular polarized(RHCP)and right hand circular polarized(LHCP)antenna respectively, are then selected and retrieved to SSH.At last,wind data from automatic weather station nearby was preliminary analyzed to confirm the reasonability and creditability of SSH output from the system.So far,the system has run into trial operation for about 1 year.
