Abstract :
On the basis of experimental research the shape of the spectra of rain agitated water surface was qualified. It was shown that for frequencies above 15 to 20 Hz the spectral density decreases more slowly than in the lower frequency areas. This spectrum area corresponds to the backscattering of the cm and mm radiowaves at low grazing angles. The quantity estimation of the RCS of agitated. surface was found for the single drops and for the artificial rain. On that basis the decision was made that, at low grazing angles the main effect in backscattering comes from the stalk and crown in place of splash at impact point, but at high grazing angles,the main effect is backscattering by the ring waves
