摘要

In this paper, studies on offshore wind farm wakes observed by spaceborne synthetic aperture radar ( SAR ) are reviewed mainly based on our previous research. Particularly, we focus on investigating wind wakes and tidal current wakes observed by spaceborne SAR of TerraSAR-X, Gaofen-3 and Radarsat-2 in high spatial resolution, in two offshores wind farms, i. e., the Alpha Ventus in the North Sea and the one near Donghai bridge in the East China Sea. Representing examples of wind wakes and tidal current wakes observed by SAR in the two farms are presented and compared. A preliminary statistical analysis on morphology of wind feature downstream Alpha Ventus is presented as well. Besides these studies on wind wakes generated by a single offshore wind farm, we show an example of wakes downstream multiple wind farms in the North Sea to demonstrate"cluster"effect of multiple offshore wind farms on sea wind.
