Abstract
The main purpose of this work is to predict the normalized radar cross section (NRCS) of two-dimensional sea surface at 30GHz according to the facet-based asymptotical model (FBAM). To examine the feasibility of FBAM in evaluating the radar returns from sea surface at higher microwave bands, some comparisons of the backscattering coefficients between FBAM and small-slope approximation (SSA) are given at 30GHz. The simulations show good agreement between SSA and FBAM for both the co-polarization and cross-polarization. Then, some numerical results in several bistatic configurations are obtained to further prove that the FBAM is an effective model to investigate the EM scattering from sea surface at higher microwave bands.
