Ocean wave observation by GPS signal

A wave observation system by GPS signal is proposed to measure wave information, such as wavelength and wave direction. In this system an arrayed GPS antenna is used to receive multi-path GPS signals reflected from sea surface and software GPS receiver is designed to process composite signal to extract wave information. According to the composite signal, the indispensible performance and characteristics of the arrayed GPS antenna and RF front-end has been analyzed by computer simulation. Autocorrelation function and Teager-Kaiser energy operator are utilized as core functions of software GPS receiver. The system has been verified that the arrayed GPS antenna can receive multi-path signals from specified measurement area and software GPS receiver can process signal very well and estimate relative time delays of multipath signals.
