On the relationship between sea surface SAR speckle and wind field
In this study, synthetic aperture radar ocean speckle is exploited to infer information on sea surface wind field. The K-distribution is adopted to model the single look complex vertically/vertically-polarized intensity speckle signal measured over sea surface under different wind conditions, i. e.,...
