Abstract :
In this paper, for moderate winds, the statistics of the field backscattered from sea surfaces are studied by simulation, by using a numerical model. It is observed that the field phase and amplitude are close to a uniform distribution and a Rayleigh distribution, respectively. However, reducing the radar resolution limit induces a departure from the Rayleigh distribution. This departure depends on several parameters: it gets stronger when the wind speed increases or the incidence angle decreases.
