摘要
A finite-difference time-domain approach for electromagnetic scattering characteristic from a two-dimensional (2-D) infinitely long target with arbitrary cross-section above the one-dimensional (1-D) randomly rough sea surface is presented. Taking the composite scattering of rough sea surface and infinitely long cylinder as an example, the angular distribution of the scattering cross-section with different incident angles is calculated and it shows good agreement with the numerical result by the conventional Method of Moments (MOM). Finally, the influence of the windspeed on the sea surface, the incident angle, as well as the size and location of the target on the composite radar cross-section (RCS) with different polarisations is investigated in detail.
