First results of GNSS-R coastal experiment in China

We report on the first time of GNSS-Reflection (GNSS-R) coastal experiment in Fujian province in the southeast of China. The experimental campaign began in September 2006 and the succeeding observation was kept until March 2007. Through the ocean reflected event recorded by the Oceanpal instruments, the direct and reflected correlation waveforms were obtained. We retrieved the Significant Wave Height (SWH) and Sea Surface Height (SSH) with these data. Then a method to compute the wave speed and direction by the delay of the autocorrelation waveforms was proposed. We present primary results here. With the continual measurements, we also studied the semidiurnal tides and paid our attention to the variations of amplitudes and phases of the tides. At last we present some problems occurred in this experiment and discussed the possible treatments to make the observing technique available in the seacoast of China.
