Asymptotic Modeling of Coherent Scattering from Random Rough Layers: Application to Road Survey by GPR at Nadir
Figure 2
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.
