Abstract :
A new approach based on the original full wave solutions for the like and cross scattering cross sections of composite (multi-scale) random rough surfaces is presented. The rough sea surfaces are assumed to be characterized by the Pearson-Moskowitz spectral density function. The probability density functions (PDFs) for the rough surface heights and slopes are assumed to be Gaussian. The backscatter incoherent like and cross polarized cross sections are calculated using this new full wave approach.
