Abstract:

Computational relationships are obtained for estimating the effect of cloud cover upon the intensity of a signal emitted by a surface source and detected at high altitude by a sensor with a wide field of view. The treatment follows the narrow-angle approximation of radiation transfer theory applied to a beam of radiation with Gaussian intensity distribution in both the angular and lateral spatial coordinates. The model of a homogeneous scattering layer, its scattering phase function approximated by a Gaussian, is used. The possibility of estimating the parameters of the cloud layer from the magnitude of the distortions introduced by it in the spectral distribution of the sounding pulse emitted by a flash-lamp, using the relationships from the present study, is discussed.
