Applications of GPS-R Technique for Ocean Remote Sensing: Results of Coastal Experiment in China

Results of the GPS-Reflection (GPS-R) coastal experiment in the southeast of China were given. The experimental campaign began in September 2006 and its succeeding observation was kept until March 2007. Through the ocean reflected events recorded by the Oceanpal instrument, direct and reflected correlation waveforms were obtained. Then the sea surface parameter Significant Wave Height (SWH) was retrieved and compared with an Ultrasonic Wave Gauge (UWG) measurements in situ which was regarded as the truth. The statistics shows that the mean error and stand deviation is less than 5.1cm and 10.1cm respectively. At last a potential way for deriving wave speed and direction with the delay of the autocorrelation waveforms was proposed.
