Sea Surface Wave InformationUsing GPS Sea Reflected Signal

摘要

In case of positioning by GPS, the direct signal from thernsatellite to the receiver is ordinarily utilized, but thernmultipath signal is regarded as one error source that deteriorate the positioning accuracy. In this paper, wernfocus on characteristics of the reflected signal, and had arnfew simulation tests. The correlator output signals arernchecked out and compared to the change of wave heightrnand the wave period.rnIn this paper we describe that in sufficient long waverncompared with reflection area size we can measure anrnaccurate wave height, and by pointing antenna beamrncenter from two directions we can obtain therncharacteristics of wave which are height, direction andrnperiod.
