Asymptotic Modeling of Coherent Scattering from Random Rough Layers: Application to Road Survey by GPR at Nadir

Figure 4

Frequency behavior of the amplitude attenuation of the coherent scattered fields and (V polarization) in the frequency band GHz, comparatively to the flat case. Results from the PILE code and comparison with the SKA and SPM2 asymptotic models for Gaussian surfaces. The upper and lower correlation lengths are mm and mm, respectively.
