Abstract
Analytical equations are derived for the useful signal reflected from the rough surface of an object and the noise signal scattered (in the single-scattering approximation) by aerosol, which is between the transmitting-receiving system and the object, in the approximation of Gaussian distributions of the field of a partially coherent laser beam, coefficient of diffusion reflection from the object, phase scattering function of the atmosphere, and the receiving aperture transmission function. The ratio of these signals is calculated as a function of the distance to the object.
