The technology of wind field data fusion can acquire the global wind field with smaller cost and shorter time,and provide high spatial resolution data for ocean surface wind field forecasting.In order to make a good use of satellite remote sensing data in sea surface wind field monitoring,this paper researches the data fusion technique using the spaceborne microwave scatterometer data of HY-2A/SCAT,METOPA/ASCAT,and Oceansat-2/SCAT.The wind field data fusion method is based on variation estimation.Taking China offshore area as an example,the fusion results of satellite remote sensing wind field data are given out.The results indicate that the sea surface wind field acquired by multi-source data fusion is better than that measured by single satellite.The ocean surface wind vector,that acquired by fusion using the satellites data mentioned above,is more consistent with the actual wind field and its character is more obvious.
