Abstract :
An approach for computing efficiently monostatic and/or bistatic radar cross section of complex target on an infinite perfect electric conductor or dielectric ground plane is presented. The approach is based on Physical Optics and Equivalent Currents Method together with the Image Theory. The last one is used to obtain the scattering from the target above the ground plane, avoiding to model the infinite ground plane. In order to consider realistic targets composed of dielectric or perfect electric conductor, they are modeled by parametric surfaces (NURBS).
