Study of Ocean Wind-field Monitoring System Based on GNSS-R

In order to get the information of ocean roughness and the precision result of wind-field retrieval,The Delay one-dimension sampling and the Delay/Doppler two-dimension sampling was analyzed and simulated based on model of Spectrum of Ocean Waves and scatter correlate power,the Z-V model of was validated.The simulation result show that the Delay/Doppler two-dimension sampling was comprehensive for describing the information of ocean roughness;the design of Doppler Delay Mapping Receiver was accomplished based on two-dimension sampling theory.The configuration of hardware,work principle was expatiated.The data processing mode of Doppler serial/ Code delay parallel was analyzed.So the reasonable way of getting scatter correlate power was present.
