Abstract

An efficient finite element method (FEM) algorithm to compute scattering from a complex body of revolution (BOR) is developed. The method uses edge-based (vector) basis functions to expand the transverse field components and node-based functions to expand the Eφ field components. The use of vector basis functions eliminates the problem of spurious solutions suffered by other three component FEM formulations. Perfectly matched layer (PML) absorbers in cylindrical coordinates are used to truncate the mesh. Because PML absorbers are available in cylindrical coordinates, the method is efficient for arbitrarily shaped scatterers. The FEM equations are solved by ordering the unknowns with a reverse Cuthill-McKee algorithm and applying a banded-matrix solution algorithm. The method is capable of handling large radar targets, and good agreement with measured results is achieved for benchmark targets.
