Abstract:

The power of the echo–signal received from a randomly rough surface with combined scattering phase function of elementary locally flat sections is studied for the case of monostatic nadir sensing through the atmosphere. Analytical expressions are derived for the average received power and delay and width of the echo–pulse from the surface with scattering phase function comprising diffuse and quasispecular components when sensing through the optically thick aerosol atmosphere. It is shown that surface roughness can substantially distort the echo–pulse shape both in the transparent and optically dense atmosphere.
