Description
We present a study of the regions of accuracy of various rough surface scattering models including the physical optics approximation and the small perturbation method. The accuracy of the models is compared for surfaces with power law and Gaussian power spectra. RMS error values between the exact method of moments solution and the models are shown over the entire parameter space studies. Results of the study also demonstrate a linear relationship between the accuracy of the methods and the moments of the surfaces.
