Abstract:

Power of return signals from a randomly rough surface with a combined reflectance of locally plane areas at a bistatic sounding in the atmosphere is investigated. An expression for a mean power of a return signal is derived for the case of sounding through an optically dense aerosol atmosphere and the surface reflectance being composed of a diffuse and quasispecular components. It is shown that the return signal shape strongly depends on the ratio of diffuse and quasispecular components of the surface reflectance as well as on the surface roughness and the state of the atmosphere.
