Abstract
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.
