|This project researches on SAR ocean wind retrieval approach and evaluates the method of DNVAR using two year s’ real SAR data and different background winds. Based on the literature review, the band, coverage, period and other related information of SAR missions are evaluate d, and the SAR ocean wind retrieval meth ods are analyzed. The trade off between DIRECT and DNVAR shows that DNVAR can impact on both wind direction and wind speed but takes more time to calculate the minimum of the cost function. Experiments are carried out using SENTINEL 1 SAR information as obs ervation, NDBC buoy data as in situ data GFS, ASCAT, WindSAT, and CCMP wind products as background data. Results show that DNVAR can improve the wind field accuracy when the background data is ASCAT and CCMP data. Especially , DNVAR wind speed results are much better than the official product of SENTINEL 1 wind data.
