Anais do XX Simpósio Brasileiro de Sensoriamento Remoto

We present in this paper the result of an analysis of the effect of wave climate, measured by the Wave Age (WA) parameter, first upon the goodness of fit of the chosen pdf used for the Synthetic Aperture Radar-SAR Ocean clutter and, secondly on the accuracy of Constant False Alarm Rate –CFAR algorithm used for ship detection. The important point of the establishment of the Threshold - T for accepting, or not, a bright pixel as a potential ship is dealt with a suggestion of T adjustment dependent on the WA value. The region of interest–ROI for the study is the Brazilian Northeast coastal and offshore area impacted or related to the large episode of oil spills in 2019.
