We have constructed a model which generates coherent time sequences of
combined simulated whitecap and glitter radiance images. The algorithm
uses a wiid wave power spectrum and generates an initial ocean wave
surface via a Monte Carlo method. The linear wave dispersion relation
is used to produce time sequences of ocean surfaces from the initial
surface. Each of these surfaces is composed of facets that are defined
by the numerical procedure. By treating each of the 'facets as a roughened
surface, glitter radiance fields are generated. The reflectivity
of each of the facets is a functional of the source and viewing angles,
with roughness as an additional parameter. The wave height acceleration
fields are also calculated from each of the ocean surfaces. A
downwardacceleration threshold is used to determine whether a particular
facet contains whitecaps and to determine the mean reflectivity.
Thus whitecap radiance fields coherent with the glitter field are generated.
The two radiance fields are then combined to generate simulated
whitecap/glitter radiance fields which are compared to field data
and results of these comparisons are presented.
