Abstract
We consider scattering of a narrow optical beam in a scattering medium by a randomly rough surface with Lambert indicatrix of local scattering. Expression for the average power of a signal recorded by the receiver is found for the Gaussian distribution of heights and rough-surface tilts. The obtained formala makes it possible to correctly describe the received-signal power both in a transparent and optically dense atmosphere. It is shown that in the bistatic sounding scheme, the received-signal power significantly depends on the surface heights variance.
