As the conventional method of moment (MoM) has some disadvantages in geometrical modeling and computational work, the high order MoM and bilinear surface technology are used in studying the scattering electromagnetic characteristics of dielectrically coated conducting targets. Firstly, the geometrical structure of the target is approximated by bilinear surface technology. Then, surface integral equations are formed. Finally, simulation calculation to representative dielectrically completely coated targets is conducted. Compared the high order MoM results with the results of literatures, good agreement is found between them. At the same time, the high order MoM greatly decreases computational load and saves computer storage. This algorithm has some value in efficiently solving electromagnetic scattering (EM)problems of coated targets.
