Abstract
It is well known that an observation of the long period gravity wave is very difficult to observe for its long period and small amplitude. In our recent research, an integrated wave remote sensing system utilizing multi-path GPS signals reflected from sea surface is proposed to measure accurate wavelength for long period gravity wave. The system is equipped with an arrayed GPS antenna that has a narrow fan beam directional pattern. It has a better performance to measure accurate wavelength than wide beam antenna in numerical simulation and it can acquire multi-path GPS signal reflected from specified sea surface in seaside experiments. In digital GPS signal processing, software GPS receiver is applied to estimate the relative time delays between multi-path GPS signals. In this paper, simulation results and seaside experiment results obtained by the wave remote sensing system are also presented.
