Abstract :
Relationships to obtain information concerning some statistical properties of sea-surface slope from statistical properties of the sea-surface intensities in remotely sensed images, considering an improved model with variable detector line-of-sight angle, are shown. A new expression between the variance of the intensity in the image and the variance of the surface slopes is derived. The association between correlation functions of the intensities in the image and surface slopes is numerically analyzed. A 1-D case is considered, and the results are presented graphically.
