Abstract

Full-wave solution of electromagnetic wave scattering from rough sea surfaces is achieved by the Finite Element Domain Decomposition (FEDD) method. The method is implemented in a non-iterative manner by dividing the computational domain into overlapping subdomains, and solving the problem in each subdomain by attaching Locally-Conformal Perfectly Matched Layer (LC-PML) at the truncation boundaries. Statistical behavior of the Radar Cross Section (RCS) is investigated by Monte Carlo simulations. The results are compared with those obtained by the standard FEM, analytical models and measurements for different polarizations, frequencies, grazing angles and wind speeds.
