  • Abstract
    The objective of this paper is to investigate the effect of a two-scale surface roughness description on the polarization coherence in circular polarization (i.e. PRRLL). Under the assumption of sufficiently smooth surfaces, the small-slope approximation (SSA) model is employed to derive a first order expression for PRRLL. In the paper the sensitivity of PRRLL to azimuth slopes is presented.
