We propose an improved semi-empirical scattering model for X-band radar backscattering from rough sea surfaces. This new model has a wider validity range of wind speeds than does the existing semi-empirical sea spectrum (SESS) model. First. we retrieved the small-roughness parameters from the sea surfaces. https://www.roneverhart.com/Jaakaapin-raikastin-Fummom-InnovaGoods/
