  • Surface Roughness - an overview | ScienceDirect Topics

    Surface roughness (standard deviation of height h RMS), causes a reduction in ground reflectivity by increasing the diffusion of the incident energy, which turns into an omni-directional incoherent scattering component.In Figure 9.13, we see that for low roughness conditions (h RMS = 0.7 cm), the coherent component of the signal is significantly higher than the incoherent part (Figure 9.13(a ...
