Numerical Simulation Bistatic Scattering from Three-Dimensional Conducting Rough Surface with UV Multilevel Partitioning Method Using Pulse Vector Basic Function

Vector wave three-dimensional (3D) conducting rough surface scattering problem solved by a UV method with multilevel partitioning procession (UV-MLP) using pulse vector basic function is developed in this paper, in which pulse vector basic function is more appropriately to be used for truly describe the vector inducted currents’ distribution along 3D PEC rough surface. For a 3D conducting rough surface scattering problem, the scattering structure is partitioned into multilevel blocks. By investigating the rank in the static problem, the impedance matrix for given transmitting and receiving blocks is expressed into products of U and V matrices. The UV method is illustrated by applying to a 3D scattering problem of random conducting rough surface. Finally, numerical simulation results are carried and discussed.
