英文摘要: Wind speed deficits behind offshore wind parks in the German Bight are estimated from satellite synthetic aperture radar (SAR) data using a new filter technique. The deficit computation requires knowledge about the undisturbed wind field, which is derived by a two-dimensional (2D) convolution filter tailored to the geometry of the wake. Both the wind direction and the size of the wind farm are taken into account. The most relevant scale for the wind speed deficit estimator (WISDEM) is the width ξ$\xi$ of the wake. Unlike approaches used so far, the proposed technique is suitable for a full automisation of the estimation process. Furthermore, the rigorous definition of the method and the reproducibility of the results can help in the consistent analysis of big data sets and the meaningful...
