An empirical relation between normalized radar cross sections (NRCS) and wind vectors, known as the geophysical model function (GMF), has been established for specific wavelengths, such as Ku-band and C-band, by using scatterometermeasured NRCS and buoy or model winds [1][2]. On the contrary, L-band NRCS dependence on wind fields has been investigated by using airborne and spaceborne Synthetic ...
