Abstract: This paper developed an efficient finite element method (FEM) to compute scattering from a body of revolution (BOR). The method uses edge-based vector basis functions to expand the transverse field components and node-based scalar basis functions to expand the angular component. The use of perfectly matched layer (PML) in cylindrical coordinates avoids the wasted computation. The method is capable of handling large, realistic radar targets, and good agreement with theoretical results is achieved for benchmark targets.
