Fig.3. Dependence of the brightness of sea surface on the solar 
azimuth angle (oq ) for pure water (curves 1) and the 50 microns 
thick oil film. covering {curves 2) at the wavelength A 0.7 
microns. Continuous lines - total brightness (sun and sky together), 
dottedilines .-. contribution of the sky radiation to the sea 
brightness only. The wind velocity w =10 m/sec and azimuth 
O6 uh 00, the solar zenith angle and the zenith angle of observa- 
tion are both 209, Br -in relative units. 
The disadvantages of our model are the possible simula- 
tion of cloudless... sky or that of complete cloudiness only 
and the neglect of the distorting influence of the atmospheric 
layer between the receiver and sea surface.In spite of that, the 
simple calculation model described above enables to carry out 
a numerical experiment and, varying a great number of experimental 
parameters, results important for practical use can be obtained.
