An approach to studying composite electromagnetic (EM) scattering from the 2-D conducting rough surface and half-buried 3-D conducting target is proposed from geometry modeling to radar cross section (RCS) calculation. A two dimensional rough surface is simulated using the spectral method, which is then converted into a continuous curved surface through inverse engineering. The target model and rough surface model are combined together into a very accurate composite model, after which the surface mesh is generated with the information on the incidence frequency. Then the physical optics method (PO) and multi-level fast multiple algorithm (MLFMA) are respectively employed to study the scattering problem. The results of the single rough surface and the combinative model are given and compared.

Key words: electromagnetic scattering, rough surfaces, geometry modeling, physical optics, multi-level fast mutiple algorithm
