Abstract :
This new semi-deterministic facet model is aimed at providing a more accurate result in evaluating the radar cross section (RCS) from large-scope 2-D ocean like surface. The modified equivalent current approximation (MECA) method is blended with Bragg components in calculating the elementary radar returns from each facet. Compared with the Kirchhoff Approximation (KA) method which have used in the published relevant papers, the MECA can take the scattering from each facet into consideration. The result obtained by this new facet model would be more accurate than the conventional one in small and moderate scattering angles.
