Abstract
We consider the problem of scattering of a narrow pulsed wave beam irradiating a randomly rough surface in the atmosphere under conditions of strong shadowing of one surface element by another. Expressions for the average power recorded by a receiver are obtained for the case where a locally Lambertian surface with Gaussian distribution of heights and slopes is irradiated by a delta impulse. It is shown that the shadowing and the atmospheric turbulence give rise to a considerable distortion of the received optical signal. The obtained analytical expressions for the received power are in good agreement with the results of numerical calculations.
