Statistical Evaluation Of The Intensity Distribution Of Sea Surface Radar Images
M. Senechal, R. Garello, A. Hillion · 2005
In this paper, the relation I = S.Z is taken as a model for the intensity of the image. S is the reflectivity (of unknown law) and Z a multiplicative noise (of known law). Two possible probability d istributions are considered ( namely D irac and uniform distribution) for the sea reflectivity and the two (theoretical) probability laws of the image intensity are derived. V arious statistical test are performed from the observed data and a probabilistic model is then deduced for the reflectivity coefficients in the case of particular SEASAT images.
