RÉSUMÉ

In the small-slope approximation of the Kirchhoff technique influence of the rescattered thermal radiation of the atmosphere on the total rough surface brightness temperature is investigated. Numerical studies of the rough surface thermal radiation brightness temperature with various values both of the surface dielectric constant and of the atmosphere optical thickness were carried out. The results show that, with an external radiation, the surface irregularities lead to increase of the rescattered component of the atmosphere thermal radiation intensity.
