Abstract: The architecture of airborne ocean wind-field retrieval system based on GPS scatter signal is proposed. The theoretic models for scattering characteristics of GPS signals from ocean surface and the wind-field retrieval are discussed. The calculation of correlation power is introduced and the correlate power curves for different ocean surface are also given. The work mode of Delay Mapping Receiver (DMR) is analyzed and one of the flight tests results is taken. The test results show that the designed DMR in this paper can receive and process correctly the scattering signal of GPS satellite from the ocean surface and the conclusion can be given which is consistence with the theory analysis.
